Tim and Nancy lived in Anchorage, Alaska. Their house was literally right downtown, but they had no indoor plumbing. They did, however, have an outhouse. The older Tim got, though, the further away it seemed to get.
One night, he decided to just skip the trip. Instead, he decided to just relieve himself right there off the front porch.
Nancy was pretty pissed about his decision. "Tim, you moron. Our neighbours can see you when you do that, you know."
"It's dark out," said Tim, "they can't see me."
"Of course they can," explained Nancy, "you're silhouetted against the porch light and they can tell what you're doing."
He'd not given it THAT much thought, so he promised his wife he'd not do it again.
Not too many nights later, though, it turned bitterly cold. Right in the middle of the night he had to piss like a racehorse. He got up, put on his slippers, and headed out of the bedroom to do his business.
He was back in two shakes (so to speak). His wife, suspicious as wives are apt to be, said, "You weren't gone very long."
"You went off the porch again, didn't you?"
"Yes, I did."
"We had a talk about this, remember? The neighbors can see you. They'll know it was you and what you were doing out there. Aren't you the least bit embarrassed?"
"Nah, they won't know it's me! This time I squatted down!"
