A man and a woman found themselves allocated the same two-berth compartment on a sleeper train. They discussed the situation and agreed to act with decorum; the man took the bottom bunk and the woman took the top one.
In the middle of the night, the woman woke up feeling cold and whispered to the man, "Excuse me, but could you get me another blanket, please?"
The man replied, "I tell you what, perhaps we could pretend we are husband and wife".
The woman giggled shyly and said, "OK, then".
"So get your own #*$%�*@ blanket" said the man.
