A husband went to work at 9 in the morning as usual. For
some reason he had to be back home later during the day
while running some errands. When he entered the house, he
was surprised to see his wife in bed with a man whose head
was between her breasts. The husband demanded, "What on
earth are you doing?"
The stranger stammered, "I'm listening to music!"
The husband shoved him aside and said, "Let me listen."
He also put his head between her breasts. He exclaimed
suspiciously, "I can't hear any damn music."
"Of course not," quipped the stranger, "You're not plugged in!"
