A businessman decided to take the afternoon off and got home about 3 o'clock in the afternoon. The house was quiet, and he went> upstairs and opened the bedroom door. His wife was in bed, and there was a strange man lying on top of her with his head between her breasts. 'What the hell are you doing?' he shouted. The man looked up and said, 'I'm listening to the music.' 'What Music?' said the husband, and he leaned over and put his ear to his wife's chest. 'I can't hear any music,' he said suspiciously.'Of course you can't,' said the stranger. 'You're not plugged in.'
