Picking up a radio, he asked and found the price to be five dollars. Suspicious, he queried, 'Is this stolen?' 

'No,' said the salesman, 'It's brand new, do you want it or not?' 

'Sure,' the customer replied. He looked around some more. Next he found a top of the line computer with printer and monitor. 

'How much?' 

'Five dollars,' was the familiar response. 

'I'll take that too!' the man said. As the salesperson is ringing up the purchases, the man asked him, 'Why are your prices so cheap?' 

The salesman said, 'Well, the owner of the store is at my house right now with my wife. What he's doing to her, I'm doing to his business.'
