"30 Rock"'s fourth season has more laughs than an evening at the Chuckle Hut, Stone Mountain, Georgia's premier comedy club (when it's not harvesting the chuckle part of a pig, and no, best not ask). Don't let the 0-15 Emmy® snub fool you. This is a "Rock"-solid season with some involving story arcs, including the search for a new TGS cast member, NBC's buyout by Kabletown, Liz resisting her "settling soul mate," and Jack sorting out a romantic triangle. This is also a particularly star-studded season, with indelible turns by Michael Sheen, Julianne Moore (sporting a wicked Boston accent), Elizabeth Banks, James Franco, Bon Jovi, and Matt Damon. Jan Hooks, too long missing in action, is introduced as Jenna's scheming mother. Jon Hamm, Dean Winters, and Jason Sudeikis return as Liz's lost loves in one of the season's best episodes, "Anna Howard Shaw Day." And only on "30 Rock" will you see astronaut Buzz Aldrin taunt the moon ("Return to the night. You have no business here.") or "NBC Nightly News" anchor Brian Williams audition his comedy act. "30 Rock" remains part of TV's elite and gleefully mocks the notion it should tone down its meta satire, smash-cut gags, and inside jokes (or as Donaghy calls it, "lefty homoerotic propaganda") to appeal to a broader audience. But after three seasons, word play that was once dazzlingly fresh and original seemed in danger of becoming strained and rote. When Tracy (Tracy Morgan) references Little, Brown, he is, of course, not talking about the distinguished book publisher, but a talent agency specializing in black dwarfs. And when Alec Baldwin's Jack Donaghy welcomes one and all to Season Four, he is referring to the name of New York's "No. 1 Asian-fusion restaurant." Not that the show hasn't lost its ability to surprise and delight, as witness clips of the failed TV series "Bitch Hunter" featuring Will Ferrell. The generous extras include deleted scenes, extended episodes, 10 audio commentaries that offer such inspired pairings as Alec Baldwin and Lorne Michaels and Jack McBrayer and Jon Hamm, and the "Ace of Cakes" episode in which the bakers prepare a cake for the "30 Rock" cast and crew. Somebody bring me some ham! "--Donald Liebenson"
