Low Necked Puns

A man is walking into an expensive restaurant when he is stopped by the Maitre'D, who tells him that he can't be admitted without a necktie. The man, late for his appointment, runs back out to his car and searches high and low. Finally, out of desperation, he grabs a set of jumper cables, ties them into a rough knot around his neck and runs back into the restaurant. The Maitre'D stares at him for a few seconds and finally says, "Alright, I'll let you in..." and then leans in and says in a low growl, "but you'd better not try to start anything."
