A Classy Bar

A man walks into a bar and the bartender says, “I’m sorry, I can’t serve you here unless you are wearing a tie.”
The man says, “Okay, I’ll be right back,” and goes to his car to find anything he can use for a tie.
All he finds is a set of jumper cables, so he ties them around his neck, goes back in and asks, “How’s this?”
The bartender replies, “Well, okay, but don’t start anything.”
