Deal Breaker!: Liz Finally Gets Hers on the Season Finale of "30 Rock"

Last night's season finale of 30 Rock ("Kidney Now") featured a host of celebrity cameos, including Sheryl Crow, the Beastie Boys, Mary J Blige, Elvis Costello, Clay Aiken, Adam Levine, Cindi Lauper, Michael Stipe, and a ton of others.

But, if I'm being honest, the real joy of the episode, written by Jack Burditt and Robert Carlock, wasn't seeing an impressive batch of musical talent performing a hilarious benefit song for Kidney Now but seeing Jack Donaghy playing catch with his father Milton (played with relish by Alan Alda).

And while Jack wasn't ultimately a match for the kidney that Milton desperately needs to survive, partially so he can finish that three-volume biography of Jimmy Carter, I do hope that Alda's Milton returns next season. I love seeing Jack alternately child-like and suspicious around his biological father and it would be fantastic to see Alda on a more regular basis.

Meanwhile, I loved how Liz's story--with her new found fame for the "Deal Breaker" lady sketches skewering the trajectory of the phrase "he's just not that into you"--propelled her to superstardom, landing her a spot on a raucous daily talk show and a book deal. That Liz is completely unqualified to give out relationship advice (and only screws up both Pete and Tracy's relationships with their wives) is precisely the point. She's a writer and her own romantic relationships have been disasters on par with the Hindenburg.

What else did I love about last night's gleeful season finale? Liz's biology-related song about kidneys, brains, and colons; Jenna's murderous half-sister Courtney; Leo Spaceman's insistence that he would remember to do the opposite of what was on those medical forms; "You have sexually transmitted crazy mouth!"; Liz's insistence that bisexuality was something "invented in the 90s to sell hair products"; Tracy's crying montage; the aforementioned game of catch; Steven Killer; Jack telling Liz that TGS has maybe two more years left and invoking Wings; Tracy's promise to the graduating class of his alma mater that they would all become president of the United States one day; Sheryl Crow and Adam Levine's European alter egos; Rainstorm Katrina. (Really, the list goes on and on.)

Best line of the evening: "A guy crying about a chicken and a baby? I thought this was a comedy show." - Milton (Go, MASH series finale shout-out!)

All in all, "Kidney Now" was a fantastic ender to another wonderful season of 30 Rock, television's best comedy. Or as Liz might say, "We sure had quite a year." Yes, Liz, we did.

30 Rock returns for a fourth season this fall on NBC.
