Young Hollywood and TVGuide.com take you behind the scenes of Parenthood and Community, two of NBC's promising fall sitcoms.
First, Dax Shepard gives you the inside scoop on Parenthood, the remake of the Ron Howard film. (He plays the Keanu Reeves role.) Then, Joel McHale, "aka Ryan Seacrest," talks about the ethically challenged lawyer (redundant?) he plays in Community, which co-stars Chevy Chase.
