A guy goes into a restaurant/lounge wearing a shirt open at the collar and is met by a bouncer who tells him he must wear a necktie to gain admission.
So the guy goes out to his car and he looks around for one of his silk ties and discovers that he just doesn’t have one. He rummages around in the back of his car and amongst a pile of grow lights and plant boxes he spots a set of jumper cables. In desperation he ties these around his neck, manages to fashion a fairly acceptable looking knot and lets the ends dangle free.
He goes back to the restaurant and the bouncer carefully looks him over for a few minutes and then says:
“Well, OK, I guess you can come in – just don’t start anything.”
