Caught in the Act

A beautiful young woman walks into an orchard and finds a lovely pond. It's a beautiful mid-summer day, and even though there's a "No Swimming" sign, she's tempted to go skinny-dipping.

Looking around, she doesn't see anyone, and the pond is well hidden, so she lets temptation get the better of her. She undresses and poises to dive in. But at that moment, the orchard owner appears from behind a bush where he has been hiding all along.

"Don't you see that sign?" he says. "There's no swimming here."

"You could have told me that before I undressed," she scolded him.

"Well," he says, "it's only swimming that's prohibited. Undressing isn't."
