A man and a woman who had never met before found themselves in the same sleeping compartment of a train. After the initial embarrassment, they both managed to get to sleep; the woman on the top bunk, the man on the lower.
In the middle of the night the woman leaned over and said, “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, with a glint in his eyes, responded, “I’ve got a better idea … let’s pretend we’re married.”
“Why not?” giggled the woman.
“Good,” he said, “Get your own blanket.”
