Jon Favreau: teddy bear, Vince Vaughn wrestler, purveyor of beautiful babies.
Jane Curtin: ignorant slut, former alien-lover, person who snubbed me after a matinee of Noises Off once.
JK Simmons: Juno's dad, Spider-Man's boss, the greatest.
Andy Samberg: Swedish Chef ringtone singer.
Jean Villepique: I don't know who this person is, but IMDB says she was in an episode of 30 Rock, an episode of The Office, an episode of Curb Your Enthusiasm and three episodes of My Boys, and that coupled with the fact that they clearly weren't playing around when they cast this thing tells me she must be some comedy genius the world has yet to know.
Rob Huebel: Human Giant, Inconsiderate Cell Phone Man and former silver fox (why did he dye his beautiful hair? Why?!).
Kym Whitley: The immortal Suga from Next Friday, Kay Kay from Reno 911!.

Aziz Ansari: Human Giant, upcoming Amy Poehler primetime sidekick, notorious Aussie xenophobe.
Nick Kroll: Former Caveman from Cavemen, which is the worst, but he also made Paula Abdul "Slap a Peach Like There's No Tomorrow" on Best Week Ever, which is the best.
Lou Ferrigno: Duh.
Carla Gallo: Notable for being the toe-sucking girl from The 40-Year-Old Virgin, which is something.
Jay Chandrasekhar: My favorite Broken Lizard member, Super Trooper, Beerfest champion, and apparently a director of several Arrested Development episodes, which I had never noticed before.
Jerry Minor: Former SNL cast member who never got to do anything on SNL, but I used to see him perform at ASSSSCAT all the time, and the guy is brilliant, I swear.
Joe Lo Truglio: The State, basically every project anyone from The State has ever done.
Thomas Lennon: Another State guy (my favorite!), and Jim Dangle, of course.
Ian Roberts: Founded the UCB when he ate 15 sandwiches.
Matt Walsh: Guy who made up that 15 sandwiches joke.

And I'm like, what? No Nick Swardson? Was he busy or something?
