Elizabeth Banks: Sex is a 'fairly ridiculous act', plus that '40 Year Old Virgin' scene

Elizabeth Banks is famous for her work in sex comedies like  "Zack & Miri Make A Porno" and "The 40 Year Old Virgin," in which she depicts a bizarre sex scene in a bathtub, so if anyone knows why sex is funny, it's her.

"Well, it's a fairly ridiculous act," she tells Esquire. "I mean, let's be honest: It's a very primal thing that you're doing and it involves, you know -- it's what they call bumping uglies, which sort of puts it in the right place. It's a horrifyingly embarrassing act. It's the most vulnerable you can be as a person, I think."

Banks, who stars in "Our Idiot Brother" alongside Paul Rudd, recently welcomed a baby boy, Felix, with her husband, Max Handelman. Being a mom puts a whole new spin on that "40 Year Old Virgin" scene.

"Yeah, can't wait for my kid to see it! Um, no," she says of the scene. "But I am never embarrassed by something that makes people laugh. I knew that girl. She's a good-time girl who lives in the Valley -- who works in the bookstore -- and goes to community college on the side, and is really into funky stuff in the bedroom. Her entire outlook on life made perfect sense to me."
