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
manage to get to sleep, the woman on the top bunk,the man on the lower. In
the middle of the night, the woman leans over and says, "I'm sorry to bother
you, but I'm awfully cold and I was
wondering if you could possibly pass me another blanket." The man leans out
and, with a glint in his eye, says, "I've got better idea..... let's pretend
we're married." "Why not?" giggles the woman. "Good", he replies. "Get your
own f***ing blanket."
