Sleeping with Rob

An American joke I am putting here for the benefit of a friend:

Sleeping with Rob

The guys were all at a deer camp. No one wanted to room with Rob, because
he snored so badly. They decided it wasn't fair to make one of them stay
with him the whole time, so they voted to take turns.

The first guy slept with Rob and comes to breakfast the next morning with
his hair a mess and his eyes all bloodshot. They said, "Man, what happened
to you? He said, "Rob snored so loudly, I just sat up and watched him all
night."

The next night it was a different guy's turn. In the morning, same thing,
hair all standing up, eyes all bloodshot. They said, "Man, what happened to
you? You look awful! He said, 'Man, that Rob shakes the roof with his
snoring. I watched him all night."

The third night was Fred's turn. Fred was a tanned, older cowboy, a man's
man. The next morning he came to breakfast bright-eyed and bushy-tailed.
"Good morning!" he said. They couldn't believe it. They said, "Man, what
happened?"

He said, "Well, we got ready for bed. I went and tucked Rob into bed,
patted him on the butt, and kissed him good night. Rob sat up and watched
me all night."
