Replying to Prank day at my school

so today at school was the senior prank....it wasnt as good as usual but it was still awsome.  In my lunch wave there was a huge food fight and everybody in the cafeteria (300ish people) were involved.  Since the principals and teachers somehow knew it was gonna happen they were all in there screaming at kids and everone ignored them.  I got hit with some soft fruit or something and i hit somebody in the chest with a rotten apple.  It was the best food fight ive ever seen.  And my real cool study hall teacher got the whole thing on video so i get to watch it on monday. Also there was a water fight on the second floor.  There were a binch of kids with water baloons but i only had a water bottle.  The prank 2 years ago was the best......a few kids printed out like 400 pages of a sheet that allowed kids to drink at homehoming and they copied the principals signature onto it.  People's parents actually mailed it back signed saying that their kid could drink.  So basically, everybody got hammered at homecoming and somhow nobady got in trouble.
