That's almost a redneck joke!!!
Here's another...
After a fine redneck wedding the groom is about as drunk as can be but the new bride stone sober. Under the covers and cracking himself up laughing he puts his hand on his wife's breast and says "If that thing could give us milk we could get rid of the cow!" Laughing heartily at his newest funny line!
A minute or so later he runs his hand down under his wife's night dress and says "If that thing could lay eggs we could get rid of them chickens!" And now he is laughing harder than before!
With that his wife reaches her hand into his pants and says "Yeah, and if you could keep that hting hard we could get rid of your brother!"

Here's a similar one:

> decided to lighten the mood slightly. So his first question was: can anyone tell me which muscle spontaneously expands to 100 times its original size within less than a second?

A young woman in the front row blushed and started to giggle, and he turned to her and said: Young woman, you are destined to be very much disapointed - its the pupil of your eye.
