Christopher Reeve

Christopher Reeve appears in the South Park episodes "Krazy Kripples" and "200".

Role
When Timmy and Jimmy start a club for cripples, Reeve comes to town to promote stem cell research in order to 'cure' his quadriplegia. Said 'research' involved the ingestion of fetuses.

He was eventually imprisoned in a manner reminiscent of the end of the movie Superman II.

Subtext
According to the DVD commentaries, creators Matt Stone and Trey Parker had been developing the idea of a Christopher Reeve parody for several years, but were deterred from doing so due to its potentially contentious nature. However, they eventually decided to go through with it after seeing his appearance on Larry King Live, in which he espoused what they perceived to be an unwarranted sense of self-entitlement, especially in relation to those people who had been born with disabilities.

Reeve does not actually consume fetuses.
