This is an old joke, but still makes me laugh.
An old farmer has a nice little pond at the back of the property. He decides to make it even nicer with a bit of lawn and a few apple trees.
One day he decides to go pick a few apples by the pond. So he grabs a bucket and off he goes. As he approaches the pond he hears voices. There is a group of young women skinny dipping in his pond. When they see him coming they all go to the deep end and yell at him: "we're not coming out till you go away"
The farmer holds up the bucket and yells back: " That's all right, I didn't come here to watch you swim naked. I just came by to feed the Alligator!"
