"While seeking revenge, dig two graves---one for yourself." ~ Douglas Horton

The urge to seek revenge is hard to resist, but sometimes the payback exceeds the original offense and leaves the seeker of revenge filled with remorse. Or at least a little bit of regret.

Reddit user OvertOperation asked "What revenge of yours hit the victim way worse than you thought it would, to the point you said 'maybe I shouldn't have done that'?"

Here are some stories of revenge gone wrong.

Way back in elementary school a friend threw a piece of chalk that hit me square in the forehead. It was the most humiliating moment for younger me as everyone who saw that started laughing their arses off.

I plotted and planned my revenge, to get back in the exact same fashion over the next couple of days. One fine day weapon in hand, I find him perfectly placed a chalk-throw away from me.

I yell out his name and quickly launch the projectile as he spins around. For some reason he had his mouth open as he looked at me and the piece of chalk flew directly into his throat. His eyes widen and he starts choking. I stood frozen in shock as he fell on his knees coughing. Luckily somebody grabbed him from behind and thumped his back, so he swallowed the piece. An adult walks in, cannot remember who it was at the time, but she looks at me and asks what happened. At this point I'm shaking realizing that I narrowly killed my friend. I say it was a mint. My friend, also shaken at this point, laughs it off saying it went straight into his throat and he didn't taste it. The adult shakes her head and says next time just hand it like a normal person and walks away.

Years later when we were moving away to another country I remind him about the incident and come clean about the whole thing. He snaps and yells "I knew it!"

This kid in my class at school kept insulting my mother, so I said to him that if he insults her one more time that I'll get him after class. "Your mum's a sl#$!" he replied. So after class I waited for him outside and when he came out the classroom I got him in a head lock.

He forced his way up out of it, but he managed to crack the top of his head off a fire alarm, gashed his head open... he was bleeding all down his face and had to go to hospital. He was off school for two weeks after that too. I felt terrible about it.

When I was about 7 or 8 there was this girl at my school that was absolutely horrible, we'll call her Cindy. Cindy would run up to you and pull your hair out, steal the toy you were playing with, eat your snack at snack time, etc. In other words, she was a real witch.

One day as we were finishing up recess in the playground, she came up to me, pulled my hair, and took some with it. That was the last straw. As the teacher was gathering everyone inside and wasn't looking our way, I grabbed Cindy by her pigtail and dragged her over to the playground. Now this playground was built weird with a sort of enclosed area in the middle of 3 bridges that formed a triangle that you couldn't get out of. Sometimes us bigger kids would jump in there during hide and seek and climb out later. But Cindy couldn't because she was shorter. So I picked her up and threw her down in there and left to go back inside. It wasn't until about an hour later when the teacher realized that Cindy wasn't in class. I didn't say where she was and it took them another half hour to find her. I got in trouble and had to spend the next week in the principals office.

And I lost my Gameboy for a month. I did regret it immediately since I was on my first play through of Pokemon Red when I had my Gameboy taken away from me. I was devastated and it was one of the longest months of my childhood. But Cindy never messed with me again.

Two days ago, actually, in my soccer game this one clumsy defender kept catching my ankles seconds after I would pass the ball away. So one play he was clearing the ball and I just wanted to lay the kid out. As he was on his plant foot swinging I hit him with my shoulder hard and as he was falling he grabbed me and took me down with him. I landed on his arm and it snapped like a twig between the wrist and the elbow. I feel awful.

When I was bullied by some local kids I filled the gas tank of their family car with grass, dirt, sticks and stones, bottle caps, pretty much anything I could jam into the tank.

I felt sorry for that poor car.

I was 11, my older brother was 16. We would fight and argue but one time I was running up the stairs away from him and he whipped the back of my legs with a long rubber chew toy. It left a pretty big, figure-8-shaped welt on my legs. I knew he was faster and stronger than me and I knew if I tried to attack him he'd stop me. So, I grabbed a flathead screwdriver and held it over the stove until it was red hot. I ran up to him and very openly went to stab him, knowing he'd stop me. He grabbed my wrist to stop my thrust (as anticipated) and I accidentaly pushed the red hot head of it into his forearm as hard as I could.

Had a neighbor yell at my younger brother about his weight and I took it extra personal. Didn't know how to get him back without getting caught. Then I figured out I could place nails just under the back of the tire so when he pulled out of the driveway he'd run over them.

Turns out he was super poor and couldn't afford the repairs. My dad had to carpool with him to work for a month or so.

I've never told anyone.

I think I was 15 and was in class and sat next to a friend of mine. He, for no reason, began to say: "HAHA your bald father" which I followed up with "HAHA your bald mother". He started crying and ran to the teacher. I honestly forgot his mom had cancer and was getting chemo.

When I was a kid I was at a local river (a great swimming spot lots of people came to). My friend pushes me in the river and naturally I came up spluttering and a little red in the face, but it was all in good fun. For the rest of the day I planned to get her back, waiting for my opportunity to push her in, until she was at the edge of the river drying off. I pushed her, but her flailing and the slippery nature of the rocks she was on made her slip on the spot, and instead of just splashing into the water, she landed on her back hitting the rocks hard, and then fell into the water.

She was winded, but thankfully otherwise unharmed. Our parents were furious at me, and I just spent the few seconds it took to get her out (felt like a lot longer to me) just hoping I hadn't broken her back or something.

A room mate poured water on me while I was asleep. So I filled all his shoes and the pockets of all his trousers with Chili Powder. I didn't realize the powder had dye in and it stained everything, including any shirts he had tucked into work trousers and a lot of items he washed with them.

A lot of the boys in my sixth grade class thought it was hilarious to try and trip people. They'd get you no matter how careful you were. Well I was pretty good at avoiding it, but when I was in gym class this kid named Joey got me hard. I was dribbling down court and he nailed me. I face planted hard. So I thought about how to get him, and I got him at lunch. He was holding a lunch tray, so his hands weren't as useful. He nailed a table and lost a tooth. I got suspended for 10 days, and a strict no tripping policy got implemented, immediate suspensions if caught.

When we were kids, my sister threw water at me and ran away so I picked up my glass of water and ran after her. I threw the water from the glass at her once I had her cornered. Unfortunately the glass had slipped out of my hand and it hit her right across her face.

Back in middle school a friend of mine threw a small wadded piece of paper at me. I retaliated by throwing the only thing I could find, which was mud close to my shoes. Smacked him right in the face with it.

It turned out to be dog poo. I still vividly remember his angry "wtf man I throw paper at you and you throw dog poo?"

My older brother was always quite horrible to me as a child and my parents never really did much about it, he was also much bigger than me so I couldn't retaliate in a physical way cause I would be swiftly cripple cross faced/walls of Jericho'd. One day I had just had enough, My revenge? He had been playing Rome Total War for a good 6 hours a day for about 3 weeks. I started a new game and overwrote his save file.

Never seen fury like it.

I regretted it at the time cause he was so angry it scared me and it made him dislike me even more. But now I praise my 13 year old self for hitting him where it clearly hurt most.

When I was little my friends kept pointing at the little girl on the box of the board game Operation and saying it looks like me. So I pointed at the big fat guy and said 'that's your mom' and didn't realize she was behind me

Coworker and I had a friendly prank war spanning two years. Close to the end of our war he "iced" my car.

Icing involves taking the hose to the parking lot every half hour and spraying a light mist over your victims car when it's below zero out. I finished my 12 hour shift to find a car encased in 2 inches of ice.

My revenge was, I thought, both more inconvenient for him and less freezing my backside off for me. I decided to take a bed sheet, drape it over his car, and only took 4 or 5 trips out with the hose the next night.

So the next morning he finds his car with a quarter inch of ice freezing a sheet to his car. When he started peeling off the sheet he pulled his windshield wipers, arms and all off of his ratty jeep.

I got a very pissed off phone call. I felt bad, the unwritten rule was "embarrassing or inconvenient, no damage". I paid for repairs, and he got his revenge. He planted a dozen pieces of smoked herring throughout my car. Took me 6 months to find the last piece. Hidden under the carpet under the back window of my car. I can still smell it, I don't even own the car anymore....

I grew up in a semi-rural area, and the neighbors used to let their dog roam free. The dog constantly pooped on our lawn (even the back lawn). My parents would kindly ask the neighbors to please keep the dog locked up, but then grumble about it to each other at home. My sister and I (8 and 11 at the time) though we would be super helpful, and get a little revenge too, so we got a shovel and flung all of it we could find at their house. And that was a lot!

Yeah, it really was a little too far, and the neighbors did not take it well. And seeing as we lived in a fairly small community, everyone found out about it too.

Had a roommate who basically let his new girlfriend move in to our house in college. She helped herself to everything in the house but never contributed. Finally she parked in my parking spot and that was my breaking point. I let all the air out of all of her tires, thinking she'd just air them back up and it would be an inconvenience. Instead she ended up buying all new tires. Whoops. Never came clean about it.
