So, what'd your school do for muck up day?

What are some awesome ideas to do on muck up day? (Remember, we aren't out to vandalize or destroy anything... just cause chaos and fun)

Here's my list so far
• 1) 100’s of helium balloons in the Callan center with signs attached (pretty hard to get them all down) -> Also put those year 8 sound beepers/rape alarms on them
