A guy goes to a nightclub and when the bouncer won't let him in the guy asks, "'Why not?"

"Because you're not wearing a tie," says the bouncer.

"But I have come all the way from the other end of town," says the guy.

"Sorry mate, that's the rules," says the bouncer.

So the guy goes back to his car to try and see if he can find a tie or something like one. He finds a set of jumper cables, ties them around himself, and goes back to the club.

"Is this all right?" he asks the bouncer.

"Well, all right then," replies the bouncer. "But I'll be watching you - don't start anything!"
