A married couple with kids old enough to start being enquizitive about sex decided to have codes when interested in love making. His dick was known as, "dirty laundry," and her kitty was known as, "washing machine."
One evening while watching tv, the husband and wife got in to a heated discussing about the show they were watching to the point that the wife didn't even talk to him for a good hour. Once she was talking again, the husband assumed all was well and asked, "can I put my dirty laundry in the washing mashine tonight?" She replied sharply, "the washing machine is broken" and stormed off to bed.
Later on that evening the husband went to bed, turned his back to his wife and started to go to sleep. The wife feeling sorry about her outburst touched her husband on his shoulder and said, "you can put your dirty laundry in the washing mashine if you like." The husband turned to face his wife and angrily said, (drum roll please) "I've already done it by hand."
