The Charles Shultz comic strip Peanuts ran from 1950 to 2000 and inspired many movies. Peanuts is referenced to several times in Arrested Development.
The characters who have walked as Charlie Brown are: George Michael, George Sr., Tobias, G.O.B., Michael, Buster and Dusty.
The episode "Good Grief" has many references to Peanuts. The episode's title is a 'catchphrase' of Charlie Brown. Several characters sullenly walk as Charlie Brown does in the animated specials, with their heads and shoulders slumped over. The background music heard during these scenes is a version of "Christmas Time Is Here (Instrumental)" from the Charlie Brown album "A Charlie Brown Christmas" by Vince Guaraldi.
It has been suggested that Peanuts's African American character Franklin played a role in inspiring Franklin Delano Bluth.
