Think Steve Mahanahan selling child clown slaves is disturbing? Enter Will Ferrell as Donald Mahanahan, the original child clown salesman and Steve's father.
After Steve is shipped off to jail for touching a clown, Donald corners the market. Donald boasts natural, home-grown child clowns that come from his seed. In case you missed it, he continues to scream it over and over. He only makes it with women have have real clown genes, so I know he's telling the truth.
How they got Ferrell to do this is beyond me, but it makes sense since his partner in crime, John C. Reilly, is a regular on the show.
