Last night on The Late Show, David Letterman, transparent Amy Poehler fanboy, snuck in a kiss right on her lips, and then forgot to show the Parks and Recreation clip. Plus: On The Tonight Show, Lindsay Lohan fidgeted her way in, out and around the cutouts of her drapey black dress as she discussed why she cancelled on Barbara Walters's 20/20 interview: "Um, you know, the timing isn't right right now. I love her. I'm a big fan of Barbara Walters ... and so when it's right she knows she'll be the first person I sit down with." After Leno, that is. As for any lingering beef between LiLo and Babs, "It's all good. I spoke to her people." Also, Miranda Cosgrove retired the iCarly "Random Dance" ahead of the final episode that airs this Friday, November 23; and Marion Cotillard and Craig Ferguson shared a few awkward and strange interview moments.
