User blog:WillTheArthurandBusterFan5050/Which "Real" Characters Do You Think Should Appear on Arthur?

After looking at the Hoprah Linseed page  http://arthur.wikia.com/wiki/Hoprah_Linseed and leaving a comment there,I started to wonder who else should appear on Arthur.

So far we have the following that have appeared such as: And more I can list.
 * Mr. Fred Rogers
 * Michelle Kwan
 * Yo-Yo Ma
 * Art Garfunkle
 * Alex Trebeck (changed to Alex Lebek (or Lebeck))
 * The Backstreet Boys (my favorite!)
 * Lance Armstrong
 * Neil Gaiman
 * Koko Taylor
 * Taj Mahal
 * Michael Fincke

What other real people do you think should appear on Arthur? These are some more examples of people that could appear on Arthur (I'm not saying they will though, plus I'm just listing random celeberties actors and athletes and even though not all I'm listing I really think should appear but you might want them to) It's just too bad these people cannot appear because they're dead: (some of them aren't my favorite and I don't know much about but heard about)
 * The Spice Girls, individually or as a whole (yes I like the Spice Girls)
 * John Stamos
 * Bill Cosby (and other Cosby Show characters)
 * Will Smith
 * Aretha Franklin
 * Jennifer Lopez
 * Annie Lennox (Eurythmics)
 * Sade
 * Payton Manning (I was also thinking of Venus and Serena Williams)
 * Toni Braxton
 * Sandra Bullock
 * Whoopi Goldberg
 * Paula Abdul
 * Phil Collins
 * Alicia Keys
 * And more I can list And like I said, some of these I listed just to list.
 * Michael Jackson
 * Whitney Houston
 * Aaliyah (not very famous but she was one of my favorite singers and I needed another example)
 * Karen Carptenter
 * Ed McMann
 * Gary Coleman
 * Bea Arthur (her last name is the first name of the title character and she was one of the Golden Girls)
 * Paul Simon (could have appeared with Art Garfunkle)
 * And more (I don't know very many others,

Well technically they can still appear, the real versions of them just couldn't voice them.

So who would you like to see on Arthur, or would have liked to see on Arthur, only it's too late now because they're dead? Be honest, and please no making fun of anyone's/ each other's choices, everyone is entitled to their opinions.
