Remember when?

[Methuselah2]

Remember when you had to wind up your watch?

An elderly man is stretched out on his back on the beach, totally nude and with an erection. An elderly woman sees him and says, "What on Earth do you think you're doing?"

The man says, "I use my penis as a watch--actually just like a sundial. And I can see by the shadow from my penis that it must be 1:00 pm."

The woman replies, "Oh, that's interesting" and then she moves along.

A while later, she passes by the man again and as she does, he says to her, "Well, I can tell by the shadow of my penis that it's now 3:00 pm." The woman nods and then continues walking.

But soon she returns and sees the man frantically masturbating. Indignantly she says, "How dare you masturbate on the beach! That's just terrible!"

And the man says, "I'm doing nothing of the sort. I'm just rewinding my watch!"
