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.

Back to the nightclub, where the bouncer says "Well, OK, I
guess you can come in. But don't start anything."
