To see which of the three Rednecks would get to marry his daughter the old farmer told them that whoever could screw his old cow the longest would win his daughter’s hand.
The first Redneck tried his best but only lasted five minutes (typical).
The second one grunted and strained and managed to last a half hour.
The third one pumped away nearly half the night.
“All right boy, ” the farmer said, “my daughter is all yours.”
“To hell with your daughter,” the Redneck replied. “How much do you want for THE COW.”
