30 Rock

The writer, actress and comedian has helmed the hit NBC show — which will have its series finale on January 31 — for seven seasons, during which time she's had two kids, been in a few movies and written a memoir called Bossypants.

As 30 Rock wraps up its seven-season run on NBC, the star talks about why he chose to take on the role of Jack Donaghy in the first place and about looking to NBC bigwig Lorne Michaels for inspiration in creating the character.

As the series prepares for its finale, the comedian talks about how Tina Fey created the character of Tracy Jordan specifically for Morgan and how she allowed him "to fly over the cuckoo nest once a week."

Fey's impersonation of Republican vice presidential candidate Sarah Palin helped draw record audiences to Saturday Night Live in the fall of 2008. The former head writer for SNL opens up about politics, satire and her Emmy Award-winning sitcom, 30 Rock, which will have its series finale on January 31.
