Videos: SNL Comes Back With Poehler, Perry And Paterson

Which is the real David Paterson?

Amy Poehler's monologue was a dream sequence involving new cast members playing her old characters, kissing Justin Timberlake, and taunts from Tina Fey and Jimmy Fallon—plus a turn from Kenan Thompson as Lorne Michaels.

Katy Perry's Sesame Street sexiness was referenced in a Bronx Beat segment—yes, Maya Rudolph appeared. Also mentioned: Bedbugs, and how they enter homes via rodents.

The Ground Zero mosque commercial had the controversial project offering gay weddings (heck, even weddings for man and animal), a pregnancy termination area, and other questionable services—only for the ad to be from the Republican National Committee.

A commercial for a hair restoration procedure that takes hair some other parts of your body.

A "Really?!? with Seth and Amy" segment on Weekend Update about nutty Mahmoud Ahmadinejad turned into a plea to repeal Don't Ask, Don't Tell—with some advice to Lady Gaga, too.

Poehler reprised her one-legged, flatulent character Amber in a skit about Showtime's female-driven shows. Also, another bedbug shoutout.

The cold open featured Kristen Wiig as Tea Party Senate candidate Christine O'Donnell and her past.

Andy Samberg wasn't a huge part of the show, but he did have a Digital Short about a movie called "Boogerman."

Musical guest Katy Perry offered up "California Gurls" and "Teenage Dream" for her performances. Of course, we sort of prefer Staten Island Gurls.
