A guy in a bar leans over to the guy next to him and says, "Want to hear a joke about managers?"
The guy next to him replies, "Well, before you tell that joke, you should know that I'm 6 feet tall, 200 pounds, and I'm a manager. And the guy sitting next to me is 6'2", 225 pounds, and he's a manager, too. Now, do you still want to tell that joke?"
The first guy says, "No, I don't want to have to explain it twice."
