A guy goes into a trendy restaurant and lounge with his shirt open at the collar, but is stopped by a doorman who tells him he must wear a necktie to get in. The guy goes out to his car and looks around for a tie and discovers that he just doesn’t have one. However, he finds a set of jumper cables in his trunk. In desperation he ties the cables around his neck and manages to fashion a fairly acceptable looking knot, letting the ends dangle free. He goes back to the restaurant and the doorman carefully looks him and his jumper-cable necktie over for a few minutes, and finally says, “Well, okay…I guess you can come in. Just don’t start anything.”
