Three guys drive to a ski range and arrive late at night. They finally find a place to stay, but when they get to their room, they find that it only has one large bed, and this is the last room in the place.  They decide,'What the heck, it's only one night' and share the bed.

The next morning, they all wake up.  The guy on the left side of the bed says, "I had the strangest dream.  I thought some guy was jerking me off."

The guy on the other side of bed is shocked.  "I had the same dream, too!"

The guy who slept in the middle says, "Well, I didn't have that dream. I had a dream that I was skiing!"
