A newly married couple returned to their apartment after being on

"Care to go upstairs and do it?" the husband asked.

"Sh!" said the bride "All the neighbors will know what we're about
to do.  These walls are paper thin. In the future, we'll have to ask
each other in code. For example, how about asking, 'Have you left
the washing machine door open' instead?"

So, the following night, the husband asks, "I don't suppose you left
the washing machine door open, did you?"

"No, I definitely shut it," replied the wife who rolled over and
fell asleep.

When she woke up however, she was feeling a little frisky herself
and she nudged her husband and said, "I think I did leave the washing
machine door open after all.  Would you like to do some washing?"

"No, thanks," said the husband.  "It was only a small load so I did
it by hand."
