What was the most evil thing you ever did?

I swapped the body parts of my sisters Barbie dolls and my Teenage Mutant Ninja Turtles action figures. I created hybrid TMNT/Barbie’s and I think I had a few G.I. Joe action figure mixed up too.

My little sister was PISSED! 😆😆😆

Harming myself years ago? That's the only thing I can think of
