A man washed up on a desert island after a ship wreck. The only other survivors were a sheep and a sheepdog.

The three of them got into the habit of going down to the beach every evening to watch the sunset.

One particular evening, the sky was a fiery red with beautiful cirrus clouds and the breeze was warm and gentle. It was a perfect night for romance. As they sat there, the sheep started looking better and better to the lonely man. Soon, he leaned over and put his arm around the sheep.

But the sheepdog, ever protective of the sheep, growled fiercely until the man backed away.

A few weeks passed by and, lo and behold, there was another shipwreck. The only survivor was Nancy Pelosi.

That evening, the man took Nancy to watch the sunset. It was another beautiful tropical evening-perfect for romance. Before long the man started to get "those feelings" again.

He fought the urges as long as he could, but he finally gave in, moved closer to Nancy and told her he hadn’t had sex for months.

Nancy batted her long, lovely eyelashes and asked if there was anything she could do to help.

"Yes," he said, "Take the dog for a walk."
