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 who placed his head on her breasts. The husband demanded, "What on earth are you doing?"
To which the stranger nonchalantly replied, "Quiet! I am listening to music!!"
The husband shoved the stranger aside and said, "Let me listen!" and placed his head on his wife's breasts.
He exclaimed in suspicion, "I don't seem to hear any music."
"Of course not," quipped the stranger, "You're not plugged in!"
