"Deliverance" joke

The out-of-state couple are camping on the shores of a lake
near a tiny hamlet. The young wife, stunningly built, decides
to give the local town folk a thrill by sun bathing in the nude.
"That's OK with me, honey," says her husband. "I'll go get
some wood for the fire."
About thirty minutes later, the husband returns to the campsite
and finds his wife in tears. One of her breasts has been
painted green, the other red and her ass is blue. "What on
earth happened to you dear?" he asks.
"Some of those rednecks from town came over and told me they
don't allow any nakedness around these parts. Then they gave
me this paint job!"
"Damn those trouble-makers! I'll fix them!" the husband shouts.
He rides into town and finds the rednecks in a bar. "Who is
the SOB who painted my wife red, green and blue!" he shouts.
A huge redneck, about 6'-8", steps forward, a shotgun in his
hands. "I did it," he bellows. "What you got to say about it?"
The husband answers meekly, "I just wanted you to know the
first coat of paint is dry."
