A man and a woman who have never met before...

A man and a woman who have never met before find themselves in the same sleeping carriage of a train.

After the initial embarrassment they both go to sleep - the woman on the top bunk and the man on the lower.

In the middle of the night the woman leans over - wakes the man and says, "I'm sorry to bother you - but I''m awfully cold and I was wondering if you could possibly get me another blanket?"

The man leans out and with a glint in his eye - says, "I''ve got a better idea... just for tonight, let's pretend we're married."

The woman thinks for a moment. "Why not," she giggles.

"Great," he replies, "Get your own damn blanket!"
