Will Arnett is seriously one of the funniest dudes on the face of the planet. In the clip above — a sneak preview sketch from the new season of Human Giant, which premieres on March 11 — he plays himself as a sex addict who gets tricked into having sex with a paparazzo wearing a Mary-Kate Olsen mask. We're not really sure if MTV will air the sketch as is, because it's pretty dirty, particularly Arnett's lines, which make the whole scene: "God, all this talk about abortions is making so wet" and "I'm gonna babysit your vagina" and "I can't believe my dick just barfed that much!"
