Dumbest thing you did as a child

[Legendary Spyro]

The F-word. Additionally, my mom found out and I got grounded haha

LOL I got in trouble for swearing when I was, like, three years
old. I was playing this military flight sim and one of the pilots
when I shot somebody on my own side said "What the hell
are you doing?!". I repeated it in front of my parents and they
gave me a time-out. That was the very FIRST time I ever said
a bad word. Good thing I was homeschooled and wasn't going
to the public schools or otherwise I probably would have learned
some even WORSE ones from other young kids my age at the
time!
