Emmy-winning TV comedy "30 Rock" bowed out after seven seasons on Thursday with bittersweet farewells but giving all its zany characters a happy ending.

The satirical show-within-a-show about the inside workings of a fictional television sketch series saw Tina Fey's hapless writer Liz Lemon try to round up her unruly cast for a last hurrah.

Along the way, unpredictable sketch star Tracy Jordan (Tracy Morgan) causes chaos, self-centered actress Jenna Maroney (Jane Krakowski) attempts to find her true calling on Broadway, and producer Pete Hornberger (Scott Adsit) finally achieves his dream to disappear without a trace.

The show's simpleton page-turned-janitor Kenneth Parcell (Jack McBrayer) finds himself in his element with his sudden promotion to head of television network NBC.

But under the jokes, the cast showed some real emotion in Thursday's hour-long series finale.

"There's a reason people don't say honest goodbyes. It's because when stuff is coming to an end, people freak out and they act crazy," Liz tells Tracy.

Despite small audiences, "30 Rock" became a cult favorite, while Liz has been a hero for single geeky women as she tackled the male-dominated world of network television, with phrases such as "what the what," "blerg" and "I want to go to there" becoming popular.
