How is this Joke...........?

Charlie marries a virgin. On their wedding night, he's on fire, and wants some dirty fun so he gets naked, jumps into bed, and immediately begins her. "Charles, I expect you to be as mannerly in bed as you are at the dinner table." So, Charlie folds his hands on his lap and says, "Is this better?" "Much better!" she replies with a smile. "Okay, then," he says, "now will you please p the p*ssy."
