A country guy goes into a city bar that 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 (a bulky string 
tie to be sure) and returns to the bar. The maitre d' is reluctant, but 
says to the guy, "Okay, you're a pretty resourceful fellow, you can come 
in... but just don't start anything"!
