At the Club.

So this guy wants to go into a nightclub, but the bouncer says -"Sorry, bud, you need a tie for this place." Our Hero goes back to his car and rummages around, but there's no necktie to be found.Finally, in desperation, he takes his jumper cables, wraps them around his neck, ties a nice knot, and lets the ends dangle free.He goes back to the nightclub, where the bouncer says...
"Well, OK, I guess you can come in. But don't start anything!"
