Victim: "Officer, someone stole my unicycle!"
Cop: "Ha Ha Ha! Was he wearing a clown costume?"
Victim: "I didn't see the thief, but I can describe the unicycle. It's not really like what you're thinking. You don't sit on top of it, you sit inside a large wheel and pedal like crazy. It looks a lot like a Hoola Hoop with pedals. Something very much like it was featured on an episode of South Park."
Cop: HaHaHaHaHa...!
Victim: "Never mind!"
