When we are in school there are certain subjects, lessons and skills that are pushed upon us even when we know, it's completely superfluous. The higher ups are always saying... "You'll need all of this, trust me." And now we know, even they knew that was balderdash. Ain't nobody ever going to need Geometry Proofs.

Redditor u/elliotsilvestri6 wanted everyone to discuss some of the things we were told by grown ups and educators about what we for sure needed to learn for the future, but as it turned out, we all knew better by asking.... What is the most useless skill you learned in high school?

I Love Pi!


I memorized Pi to like 20 places. I am 42 years old and I have never, EVER used this in real life. -Words-Words-Words-

It's kinda funny that so many people memorize pi. Even technical people don't usually need it past 5 or 6 digits in common usage, and in the cases that you do, you are definitely using a computer or calculator which stores the value anyway.

Numberphile solved that 39 digits is sufficient to calculate on the scale of the universe with the precision of a hydrogen atom. OddGambit

To Test or not to Test. 

How to take a test about taking a test. themanincenterback

Similarly, how to write essays that, aside from proper grammar, have absolutely nothing in common with documents/communications in the real world. Beleynn

Nostril Play. 

I learned that I could stick a pencil up my nose and it would cause me to sneeze. I would do it so much that the teacher would get annoyed and tell me to leave the classroom or go to the nurses office. Great way to get out of class for a few minutes. jparks2305

Not a Stunt. 

We had a self defense week in PE. It was literally just some guy, who probably watched some YouTube videos, doing demonstrations on his 12 year old kid. Buddy rear naked choked his son and is calmly explaining how to sink it nice and deep, meanwhile his son is furiously tapping on his dad's arm in a vain attempt to get this physcopath to release him. We had an entire week of domestic violence. dalinar14

How to disassemble & assemble a ballpen within 10 seconds. MrChocolate007

I always thought people who could do that were so cool... still do. vaani23

The Cube. 

In my Microeconomics class I learned how to solve a rubic's cube in under 40 seconds. It has helped me with nothing in my real life. It wasn't required during class, but my friends and I would do it during group assignments (after we got the work done mostly). Lead5alad

Line by Line. 

Detailed literature analysis.

Figured out very early that if you could just find some way to read the text as erotic, our teacher'd practically clap her hands with joy. PM_ME_YOUR_WORRIES

Forever NOT Plaid. 

Matching plaids (matching the seams and pockets). I spent weeks making a suit jacket that had a plaid pattern in home etc. Every step had to be approved by the teacher before I could move to the next step. I have never ever worn plaid since, nor have I wanted to make anything else that's plaid. I think I wore the jacket once, and my mother wore it maybe twice. But I can match a mean plaid. A+ all the way baby. gnapster


I spent years listening to math teachers tell me I wouldn't always have a calculator in my pocket... that was before we carried portals to the entirety of human knowledge in our pockets, so yeah. Max_Fenig

Killing Kermit.


In biology class, I learned how to dissect a frog and identify its organs.

It's a skill I've never needed since. Back2Bach
