Not a story about me but this kid I used to know named Scott W.
He was doing the bible reading talk and was a short kid so had to stand on a box as kids often do to see over the podium. During his talk he was moving around a little bit, started to lose his balance, grabbed the podium to steady himself, lost his balance, fell off the box, knocked over the podium that knocked over the microphone, and on his way down hit the curtains behind him and tore them down on his way. The way the story goes he just got up and locked himself in the bathroom for the rest of the meeting.
What's funny (sorta) is that this is the same kid who later had part of his weenie cut off because for some reason he decided to pee out his window and it fell shut while he was doing it.
