Skinny Dippers
Ron, an elderly man in Australia, had owned a large farm for several years. He had a large pond at the back.
It was properly shaped for swimming, so he fixed it up nice with picnic tables, horseshoe courts, and some orange and lime trees.
One evening the old farmer decided to go down to the pond, as he hadn't been there for a while, and look it over.
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. He made the women aware of his presence, and they all went to the deep end.
One of the women shouted to him, "We're not coming out until you leave!"
Ron frowned, "I didn't come down here to watch you ladies swim naked or make you get out of the pond naked."
Holding the bucket up Ron said, "I'm here to feed the alligator."
