A man and a woman who lhave 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, Im sorry to bother you, but Im 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, Iive got a better idea . . . lets pretend were married.

Why not. the woman giggles.

Good, he replies. Get your own damn blanket.
