A man and a woman who have never met before find themselves in the
same
sleeping carriage on a train. After the initial embarrassment they both
go to sleep-the man on the top bunk, and the woman on the lower.
In the
middle of the night the man leans over, wakes the woman 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 woman leans out and, with a
glint in her eye, says, "I have a better idea, just for tonight, let's
make pretend that we're married."
The man says happily, "OK! Sure!"
The woman says, "GOOD. Get your own blanket!"
