30 Rock concluded its seven-season run this week, inspiring as many misty eyes as laughs. Tracy's dad finally comes back from buying cigarettes, Jack sets sail and comes up with the brilliant idea of clear dishwashers, Jenna admits she's never met Mickey Rourke, and Liz unknowingly picks a playground fight with her own husband. The one-hour finale is so full of hilarious one-liners that I'm wondering if the writers saved up all the best ones for last. Conan O'Brien turns up (kind of), Julianne Moore and Salma Hayek return, and even Al Roker gets in on the action. In the end, the entire show may have taken place inside Kenneth's Rockefeller Center snow globe. What's your take: is the final episode everything you hoped it would be, plus the stars of Law & Order: Special Victims Unit?
