3. David Beckham
David Beckham's name has been associated with The Simpsons for various reasons in the past, but an appearance has yet to come to light. In the episode "Marge Gamer", Lisa, Janey, Sherri and Terri all watched the movie Bend It Like Beckham and were inspired to join a soccer (football) team in Springfield - though Beckham himself was not a part of the episode in any way. However, the other associations that Beckham has with the series make an appearance extremely unlikely, unfortunately. When the Simpson family's alternative Christmas speech aired in 2007, Marge said about her marriage that "our union is as solid as the union between your David and Posh Spice. Oh, he did that? With his assistant? That's so sad. Okay, moving on..." As a result, Beckham is said to have turned down the opportunity to appear on the show. However, if 2010 rumours are to be believed, the producers of the show turned down the opportunity to have Beckham cameo on the show because they didn't consider him to be famous enough. That is, of course, complete and utter balderdash and an appearance from the mega-star would undoubtedly prove a massive hit with global audiences. That trademark squeaky voice would suit an animated caricature of Becks so very well.
