One night, as a couple lay down for bed, the husband gently<br />> taps his wife on the shoulder and starts rubbing her arm.<br />The wife turns over and says: "I'm sorry honey, I've got a<br />gynaecologist appointment tomorrow and I want to stay<br />fresh." The husband, rejected, turns over and tries to<br />sleep. A few minutes later, he rolls back over and taps his<br />wife again. This time he whispers in her ear: "Do you have<br />a dentist appointment tomorrow too?"
