Naughty+Naughty!

Without getting yourself into any NEW trouble, what is one of the naughtiest things you've ever done? How old were you? What were you thinking at the time? Why did you decide to do it, or was it something that just sort of "happened?" How did you feel if/when you got caught? Was anyone else with you? Were they accomplices or victims? Did anyone else get into YOUR trouble instead? Did you learn a lesson? Elaborate, and don't leave out any of the juicy details!
