So this year the senior class did an awful senior prank... they wrote something profane on the football field (which they weed wacked out pretty quickly), stuck a picnic table in a tree, and threw trash all over the campus. Now, just, btw, they dedicated their yearbook to the maitenance staff... and they threw trash all over the school? Kinda stupid.

Anyone have some good ideas? Most senior pranks I've heard are just really stupid sounding... but I heard one where someone painted a mural on the cieling of one of their buildings. I'd like to do this... paint a mural on the courtyard. BTW, the mural that the person painted and that I'd paint wasn't offensive... it was just a painting of the sky I suppose. Not really a "prank..." but I dunno.
