Mrs Beckham wants to buy a microwave. So she goes in and asks the salesman, "How much for that microwave?" The salesman replies, "We don't sell Microwaves to thick Beckhams." So the next day she dyes her hair red, dresses in disguise, and goes in and asks the same question. The sales clerk answers, "We don't sell microwaves to Beckhams." So the next day she puts on a bowler hat, suit, wig and false beard and goes and asks the same question. The salesclerk replies the same way. Posh then asks how he knows she is Mrs Beckham. The clerk says, "That isn't a microwave it's a TV."
