We pulled the clock off the wall and put it in someone elses bag, trying to frame them for the theft. Sadly they noticed before they left the classroom.

OH THAT REMINDS ME! Another time we tried to put a sewing machine (Yeah, they made us all do crap like that when we were 11 ) in someone's bag but surprisingly, it didn't fit, so we made do with putting a load of ribbons in there instead.
