This is for Charles Darwin as he appears in The Simpsons, for Charles Darwin in real life, see a separate article.

Charles Darwin (February 12, 1809 - April 19, 1882) was a famous scientist. An actor portraying him appears in the commercial to promote Mr. Burns' running for governor of Springfield[1]. In "The Monkey Suit", he is portrayed as an evil and cowardly drunk and makes out with Satan[2]. His voice is quite similar, if not identical to, Sideshow Mel's voice.
