I LOVE kick me signs. My favorite thing to do is bring one into the dorm and stick it on the back of a Bully. The reason? Bullies won't run away screaming after they've been kicked, and no one can be busted in the dorm. This ensures that I have a lengthy, pleasureable kick me experience.
I also like to put one on Sheldon if he is riding a bike. I then grab a nearby bike and follow him as he is kciked by the townspeople.
