* BilingualBonus: The "Guatemalan love song" that Jane Lynch sings had Spanish-speaking audiences laughing. It's not a love song.
* DawsonCasting; 19 year old Creator/KatDennings as 16 year old Marla.
** Inverted with 23 year old Creator/SethRogen as Cal who is implied to be much older.
* DyeingForYourArt: The chest-waxing scene? Yeah, one hundred percent real. ''Ouch.'' For the obvious reason, this was a one-take scene. In fact, at one point they almost ripped off Steve Carell's ''nipple'', because they forgot the stuff that you're supposed to put on nipples to prevent them from being ripped off. You can also see his blood starting to bubble out, as noted in the commentary.
* EnforcedMethodActing: See above.
* HeyItsThatGuy:
** Creator/SethRogen and Creator/PaulRudd are Andy's co-workers.
** [[Series/{{Glee}} Sue Sylvester]] is Andy's boss
** Creator/ElizabethBanks is a hot bookstore employee.
** Kevin Hart is a belligerent customer.
** Mindy Kaling is David's ex.
* RealLifeRelative: Steve Carell's wife Nancy Walls plays the teen clinic sex counselor. Creator/LeslieMann, who plays Nicky, is married to Judd Apatow.
* StarMakingRole: For Steve Carell.
* ThrowItIn: All of Andy's exclamations during the waxing scene were improvised by Steve Carell out of the real pain he was going through. Apatow kept separate lists for profane and non-profane ones, so they could mix and match as they pleased.
