A newlywed couple returned to their apartment after being on their honeymoon.
"Care to go upstairs and do it?" the husband asked.
"Shh!" 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."
