Good for a laugh jokey joke

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, "How about a nice juicy T-bone steak, with fries, peas, and a salad?" "Sure," replies the bartender, "that'll be four cents." "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 upstairs with your wife?" The bartender replies, "Same thing I'm doing to his business down here."
