Talking about funniest thing in Bully, I dunno.
Talking about carnival rides, in my town there was never a Ferris wheel nor a Rollercoaster. The most dangerous ride is called Kamikaze and it consists of two huge hammers. When the ride starts, the hammers move left-right, like that hypnotizing watch. It goes faster and faster, and soon it is turning in circles. When the hammer is in the air, you're upside down. The hammers don't move together: when one goes left, the other one goes right.
PS. I know that the explanation is fucking hard, but try to understand.
