A husband went to work at 9:00 a.m. 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 find his wife in bed with a man whose head was between her breasts. The husband demanded, "What the hell are you doing?"

The stranger stammered, "I'm listening to music."

The husband shoved the stranger aside and said, "Let me listen."

He then placed his head between her breasts. He said suspiciously, "I don't hear any damn music."

"Of course not," quipped the stranger, "You're not plugged in!"
