I was a troubled child ... ok, so I didn't do anything HORRIBLE, but here's my list:

Snuck out with my friend at night to light off <i>illegal</i> fireworks at the neighbors. (hehe, I still do that)

Brought lighters to school and burned people's homework in Spanish class (what an idiot i was in junior high)

Cheated on a test (again in junior high)

Made a cheating website and got caught (junior high sucked, in the words of my friend "I hate my past, I wish I could go back in time and punch myself in the face.")

I (or I should say "we") bugged the crap out of the girl that lived across the street from me. I mean, it was bad, I'm surprised the cops didn't get involved. (Did you guess that this was in junior high, too?)

I attached a bucket full of eggs to the cieling of our auditorium and attached a string so I could dump them on the principal of my school. Unfortunately the assembly was later than I had thought, so I was found out before then. (I regret that actually, but it was in High School)

My junior year I got caught "hacking" the network at school, so I couldn't use a computer that was networked for the rest of the year. (That wasn't that bad, since it wasn't nearly as bad as they made it out to be, and they realize that .... now.)

I smuggle illegal fireworks across statelines frequently. Who doesn't?

Well you choose which one is the "worst"
