A guy goes into a classy bar. This bar has a dress code, and
the maitre d' demands he wear a tie. Discouraged, the guy
goes to his car to sulk when inspiration strikes: He's got
jumper cables in the trunk! So he wraps them around his
neck, sort of like a string tie and returns to the bar.

... The maitre d' is reluctant, but says to the guy; "Okay,
you can come in... but just don't start anything"!...
