Playboy.com: So the scenes where you and Ted are getting down…you’re just there by yourself pretending this toy is ravishing you?

Barth: [Laughs] Yeah, that was pretty challenging. For weeks I was telling Seth, “How are we going to do the sex scene when there’s nothing there? Am I just going to be on the table, spread-eagle, with nothing on?” And he’s like, “No! On the floor!” [laughs] So that was hilarious to shoot, and we didn’t do the sound effects when we filmed it. So we were in the studio at Family Guy pretending to have sex. Sexual moaning sessions—we were purple by the end of it.
