Three couples (friends) travel together to a resort hotel, only to find that their reservations have been screwed up and they all have to stay in one room.
There are 2 king-sized beds and it is decided that the men will all sleep in one, and the women in the other.
In the middle of the night, the guy in the middle wakes up and says to the man next to him, "Let me out, I have GOT to get to my wife! I have the biggest hard-on I have ever had and I've got to get to her NOW!"
The other guy says, "O.K. Do you want me to come with you?"
"What the hell for?" asks the other.
"Because that's MY dick you're holding!" he says.
