The drama 'Parenthood' (Tue., 10PM ET on NBC) is all about family -- in case you couldn't have guessed that already from the title. But sometimes, parenthood can take many unusual forms. On the latest episode of the show, Crosby Braverman (Dax Shepard) introduces his son to his parents (played by Craig T. Nelson and Bonnie Bedelia). Things don't go necessarily as everyone might want, but that doesn't mean that things go badly.

"I'm a father," Crosby says. It turns out that he had a child with a woman that he barely knows. "I didn't know she got pregnant," he adds. "And then she showed up a few months ago, with a boy. ... He's amazing." And then, everything sort of works out. The lesson -- as always on the show -- is that family is where you find it. And that sometimes the most unplanned things can be the best things of all.
