"Snail car" joke

There was a snail who went to a car dealership one day. The dealer came out and asked "How can I help you?"

"Well," says the snail, "I want a car, but not just any car. I want it to be the fastest car you have."

"Okay," the dealer replied, "Anything else?"

"Yes," the snail said. "Could you paint it green with bright yellow S's on it?"

"Um, okay. It will be ready by next week. Come get it then."

"Great," said the snail and he left.

The following week, the snail returned and was overjoyed to see his bright green new car with yellow S's on it. The dealer looked at him and said "Just one question. Why did you want our fastest car painted bright green car with S's on it?"

The snail replied, "So that when people are walking down the street, they will turn and look and say' Look at that S car go!!!'"
