Watch: Paul Rudd Uses Viagra In Red Band Trailer For 'This Is 40' Plus Two New Featurettes

The red band trailer usually delivers nudity, foul language and all kinds of other stuff they can't show general audiences without some concerned parent gasping at the horror of it all. This one for "This Is 40" has none of those which leaves us asking why it was designated with that tag. Was it Paul Rudd's anus? The use of the word 'dicks'? The suggestion that Megan Fox isn't wearing any undewear? We're sure the stuffed shirts at the MPAA have their reasons, but anyway you can check out the not-so-naughty work below.

As you already know, the movie is a spinoff from "Knocked Up," with Pete and Debbie -- Rudd and Leslie Mann -- approaching middle age, trying to change their lives and in doing so, affecting their kids, careers and more. Megan Fox is still here to remind everyone that her body is magnificent, with Jason Segel and Chris O'Dowd hilariously agog as they try to make their move. Otherwise, it's a lot of footage we've seen before, with a couple new scenes, including Pete's use of Viagra.

If that's not enough, there are two more featurettes which go behind-the-scenes of the production as well. "This Is 40" blows out the candles on December 21st.
