I saw in the Missoula paper that a U of M student was arrested for climbing a building on campus and impaling a jack o lantern on the spire of that building.
I've always appreciated a good prank. Even more so when the prankster has to spend some of their own money and really go the extra mile to pull it off.
Toilet paper a house? Did that in junior high school. Plastic fork/pink flamingo somebodys lawn. More work, but it's already been done.
Now the guy who hired a crane to pick up another guys VW bug and set it on his deck in his backyard, THAT is what I'm talking about!
What are some of the good ones that you've heard?
