One of the biggest problems for a unicyclist is the hammerheads who all tell the same jokes and think they were original. Here are some of my favorites.
Joker: Someone stole half your bike!
Reply: Someone stole half your joke!
Joker: Where did you lose the other wheel?
Reply: Around the head of the last guy who asked me that question.
Joker: When are you going to buy the rest of the bike?
Reply: When are you going to take off your training wheel?
Joker: Where is the rest of the circus?
Reply: Searching for the rest of your joke.
Joker: Are you a clown?
Reply: Yes.
