Thought everyone might enjoy this-

There was once a snail that was sick and tired of his reputation for being so slow. He decided to get some fast wheels to make up the difference. After shopping around a while, he decided that the Datson 240Z was the car to get. So the snail goes to the nearest Datsun dealer and says he wants to buy the 240Z, but he wants it repainted to read 240-S

The dealer asks, "Why?"

The snail replies, "S’ stands for snail. I want everybody who sees me roaring past to know who's driving."

Well, the dealer doesn't want to lose the unique opportunity to sell a car to a snail, so he agrees to have the car repainted for a small fee.

The snail gets his new car and spent the rest of his days roaring happily down the highway at top speed. And whenever anyone would see him zooming by they'd say "Wow! Look at that S-car go!"

That's a funny one. I heard it from the 80s movie "Trading Places" with Eddie Murphy and Dan Ankroyd.
