The old farmer had a large pond in the back, fixed up nicely with picnic tables, a barbecue pit, horseshoe courts, and some apple and peach trees.
The pond was properly shaped and fixed up for swimming when it was built.
One evening, the old guy decided to go down to the pond and look it over. He hadn't been there for a while. He grabbed a five gallon bucket to bring back some fruit.
As he neared the pond, he heard voices shouting and laughing with glee. As he came closer, he saw it was a bunch of young women skinny dipping in his pond. As he approached, he made the women aware of his presence.
At once, they all went to the deep end.
One of the women shouted to him, "We're not coming out until you leave."
The old man frowned, "I did not come down here to watch you young ladies swim naked, or to make you get out of the pond naked."
Holding up the bucket, he said, "I'm here to feed the alligator."
Moral: Old men can still think fast!
