3 in a bed.
Three men go on holiday abroad together. The tourist office informs them that there is only one hotel in town with vacancies. The lads go along there, only to be told by reception that there is just one available room left in the hotel. They are not keen, but as it is their only option, they take the room for one evening and share its only bed.
That night, they all enjoy a good night's sleep. In the morning, the guy on the right side of the bed says,
"I dreamt I had the best *ank last night."
The guy on the left side says,
"That's funny, I had the exact same dream!".
The guy in the middle says, "I dreamt I was skiing."
