There's some videos on NBC with Steve Carell giving baby advice, John Krasinski talking to the baby and Jenna & Angela talking about when Jenna found out about her pregnancy.
I posted in the Steve Carell spot too, but figured you guys might like to see it too. You can submit questions for him to answer at a press event for his movie Dan In Real Life. There's a couple of them already - go post yours! :)
