ROTFLMAO!!!
That reminds me of when I went to highschool. They had one of those self locking gates in the library. We use to pull the strips out of the book bindings and hide them in the notebook bindings of people we didn't like. Hilarious!!! The unsuspecting person would ALWAYS walk briskly into the gate, do a flip, then get bodyslammed on the floor.
Yea, yea, I know, we were cruel, flame me, I don't care. We were in highschool, and that was many years ago. Even at that, I still laugh when I think about it.
