"Same as what I'm doing to his business."

A man walks into a bar one night. He goes up to the bar and asks for a beer.
"Certainly, sir, that'll be 1 cent."
"One penny?!" exclaimed the guy.
The barman replied, "Yes."
So, the guy glances over at the menu, and he asks, "Could I have a nice juicy T-bone steak, with fries, peas, and a salad?"
"Certainly sir," replies the bartender, "but all that comes to real money."
"How much money?" inquires the guy.
"Four cents," he replies.
"Four cents?!" exclaims the guy. "Where's the guy who owns this place?"
The barman replies, "Upstairs with my wife." The guy says,
"What's he doing with your wife?"
The bartender replies, "Same as what I'm doing to his business."
