For Molly Giangreco, a photographer in Omaha, Nebraska, one of those moments came last month as she was snapping the last few shots of a wedding party downtown.
As she gathered the groomsmen for a few final pictures on the strip, "this girl on a scooter and her husband came rolling through," Giangreco told Buzzfeed News.
It was unclear if the woman even knew that she had just photobombed a wedding photoshoot, but when the groomsmen started cheering, asking her to come back through again, she didn't hesitate.
"She just nailed it with her facial expression," Giangreco remarked.
After one final pass through, the woman was gone.
It wasn't until Giangreco was editing the photos on July 4 that she decided she wanted to find the woman, affectionally dubbed "scooter girl."
So she posted the photos on her photography business's Facebook page asking the community to help her find the woman so she could see the joy that she had spread that day.
It only took an hour for Facebook to do its thing and track down the woman, Kenyatta Jefferson, a local business owner from Omaha, who left a grateful comment on the post:
Jefferson was tickled by the reaction, and has since embraced her "Scooter Girl" persona, telling Yahoo Lifestyle:
"I love doing spontaneous things and making people laugh. And this one happened to go viral."
And people were clearly loving the joy Jefferson was bringing in the photos.
Jefferson was perhaps more inspirational than she even realized.
Many people started tagging Ellen DeGeneres to try to get Jefferson on the show.
It certainly seems like something Ellen would love.
So if you're reading this, Ellen, get Scooter Girl on your show STAT!
With all of the negative news out there, it's always refreshing to see heartwarming stories like this.
Giangreco echoed those sentiments, saying:
"Some people might get mad about things like this happening on their wedding day, but this is a story about embracing whatever happens."
We couldn't agree more.
