There once was a rather prudish couple. They were so uptight that they had to refer to sex as "doing the laundry". So one night, the husband's feeling rather randy and says to his wife, "Hey honey, do you feel like 'doing the laundry' tonight?" She responds, "No thanks dear. I'm not really in the mood." A few hours later, the wife feels pretty randy. She says to her husband, "Still up to doing the laundry?" He responds, "No, it was a small load so I did it by hand."
