"The Faster you are" joke

Tom P., the Olympic Gold Medal runner, was on his way to a club with some friends.

At the door, the bouncer turned to him and said "Sorry, mate, you can't come in here - no denim."

Tom was quite annoyed at this and retorted, "Don't you know who I am? I'm Tom P."

"Then it won't take you long to run home and change, will it?" replied the bouncer.
