A farmer arranges with his neighbour to have the neighbour bring his bull over to inseminate the farmer’s cow.
While the bull is doing the business with the cow,
the farmer’s son and the neighbour’s daughter are leaning on the fence watching the whole thing.
The farmer’s son nudges the neighbour’s daughter, winks and says to her,
“You know, I wouldn’t mind doing a little of what that bull’s doing.”
“Go right ahead. She is your cow, after all!”
