This guy had a bet with his cousin on who could get the best grades, with the winner getting to do whatever they wanted with the loser's hair.
Writing on Reddit, he said: "In the beginning of the school year as motivation for school/fitness, my cousin and I decided to have a GPA/pushup bet. She ended up getting a 4.0 across the board, which I wasn't even close too [sic]."
He added: "Luckily she's a pretty artistic and talented kind soul who IMO made my hair pretty cool[sic]!
"The winner could do whatever they wanted to the other persons hair, she definitely was pretty kind with it!"
