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. In "The Monkey Suit", he is portrayed as an evil and cowardly drunk and makes out with Satan. His voice is quite similar, if not identical to, Sideshow Mel's voice.
