Washing machine

A husband and wife were lying in bed one night. (Since they have small children, the universal-parent coding system for sex is washing machine.) The husband turned to his wife and said in a seductive voice, "washing machine." The wife, being the hard working parent she is, was tired and she said, "Not tonight, dear; I'm tired." He rolled away. Five minutes later, he rolled back over and repeated "Honey, washing machine." She said, "I've got a headache." He rolled away again. Ten minutes later, the wife, feeling guilty, turned to her husband and said, "OK, washing machine." He replied. "That's OK. It was a small load and I did it by hand."
