OK, so your kids might not get what a big deal it is that Robin Williams is returning to TV after nearly three decades. After all, when they hear the word “Nanu-Nanu,” they might think it's the latest Icelandic pop star. But that’s why Williams’s new David E. Kelley comedy is stacked with star power—Sarah Michelle Gellar (whom they’ll recognize as Buffy the Vampire Slayer) plays the straitlaced daughter to her nutty ad exec dad.
Watch It: The Crazy Ones premieres Thursday, September 26, at 9 p.m. ET on CBS.
