Alec Baldwin’s ‘SNL’ Appearance, According to the ‘SNL’ Sketch Predictor

The Set

I've been to the future and brought back this sketch-by-sketch rundown of tomorrow's episode of "Saturday Night Live." Or is it just a series of very educated guesses? Read our "SNL" Sketch Predictor and judge for yourself.

11:30 PM Cold open: Maria Bartiromo (Nasim Pedrad) reports on the Dow, which drops so precipitously that pieces of her studio set and, eventually, clothing, are removed by repo men.

11:37 PM Opening monologue: Leonard Nimoy starts delivering the monologue as Alec Baldwin, until Baldwin emerges from the wings and reluctantly takes over.

11:42 PM Commercial parody: A narrator (Jason Sudeikis) walks you through which iPad apps can facilitate the user's plans to burgle a private home.

11:45 PM Republican Presidential debate: The candidates try to outdo each others' conservative credentials — for instance, Rick Perry (Baldwin) decries the impingement of freedom highway guardrails represent — while Michele Bachmann (Kristen Wiig) pledges that, if elected, she will build a time machine to go back and sabotage the development of the polio vaccine.

11:56 PM Starbucks barista Ray (Baldwin) is rude to and unimpressed by all his customers — even one who happens to be a Hollywood legend (cameo by Steve Martin).

12:03 AM Digital Short: A video for The Lonely Island's "Mama," in which Baldwin plays the titular character, in drag.

12:10 AM [Radiohead performs.]

12:18 AM Weekend Update features Aunt Linda (Wiig) on the summer's biggest movies (none of which she likes as much as "Drive"); Michael Stipe (Paul Brittain) on the breakup of R.E.M.; and Snooki (Bobby Moynihan) on her time in Italy.

12:30 AM Tony Bennett (Baldwin) records tracks for "Duets III" with Justin Bieber (Elliott), Nicki Minaj (Pedrad), and LMFAO (Jay Pharoah and Fred Armisen).

12:41 AM Queen Elizabeth (Armisen) takes Kate Middleton (Vanessa Bayer) for a refresher course in how to behave like a princess, taught by a doddering nonagenarian Sir Herbertram of Welch (Bill Hader, doing a British version of Herb Welch, his recurring reporter character).

12:49 AM [Radiohead performs.]

12:56 AM Whitney Cummings (Bayer) attempts to prove that her show really was recorded in front of a studio audience that loved what it saw.

1:01 AM Goodnight!
