Dream of Skiing

So, these three good friends arrive at a ski lodge late at night, and are told there's only a single room available. Fortunately, it has a king-size bed and they agree to share the room, quickly going to bed in order to hit the slopes early the next morning.

The next morning, while they're suiting up, the man that slept on the left side of the bed says, "You know, I had the strangest dreams! I kept dreaming that someone was jerking me off!"

"That's funny," replies the man sleeping on the right, "I had the same kind of dream!"

They both turn and stare at their friend that had slept in the middle.

"Don't look at me!" he exclaims. "I dreamed about skiing all night!"
