A snail walks into a car dealership and buys the fastest car on the lot. The salesman is amazed and asks, "What are you planning to do with this car?"
The snail replies, "I want you to paint a big 'S' on the sides and the top of the car."
Curious, the salesman asks, "Why would you want that?"
The snail grins and says, "So when I drive around town, people will say, 'Look at that S-car-go!'"
