"I want to go as a clown," you say, although you're not sure why. As a little kid, you were afraid of clowns, although you're over it now yet you still never particularlly liked them.
"Very well," said the saleslady. "We can even do your makeup right here. What type of clown do you want to be?"

"There are three basic types of clowns. The whiteface that acts as a sort of straight man for the other clowns, like Jerry Seinfeld does on his show. Then there's the auguste with white around the eyes and mouth, that can either be a prankster or the butt of pranks. And finally there's the hobo, which can be either happy or sad, and is always the butt end of the other clowns jokes."
