That is the best senior prank EVER. EVER.
At my high school we used to have bird feeders. The senior class I wanna say 3 or so years ago put laxatives into the feeders. HAHAHAHAHA
I thought that was pretty brilliant, but the giant dick-on-the-roof thing is funny too.
Speaking of which, that Lonely Island CD has a track called ****-in-a-box.
