These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Get Him to the Greek
Alternate Character Interpretation: Whether Aaron Green's hesitance to party is because he is attempting to remain professional and watchful of his charge or is he too socially awkward to party?
Awesome Music: Infant Sorrow's songs alternate between catchy, hilarious, or both.
Sarah Marshall's new show, where she plays a blind doctor. The opening credits are in English and braille.
Ear Worm: "I've the clap! You've got the clap!" Or, "Stroke the furry wall!"
Pretty much all of the Infant Sorrow songs are these: "Why won't you call and come home? Please call and come home..." & "Can you hear what's going on? I'm comin up...I'm comin' up...I'm comin' up...I'm comin' u-u-u-u-up!"
Also, both Jackie Q's songs are incredibly catchy.
Heartwarming Moments: The video tape scene. Jackie keeps insisting they should make a sex tape and Aldous says he doesn't want to, because he just wants to lie there and kiss her.
The fact that the first song of the concert at the end of the movie was the one that his father suggested he open the concert with.
Ho Yay / Ambiguously Bi: In one of the party montage scenes, Aldous is seen briefly snogging a man. In another, he and Aaron are leaving a gay bar. Aldous also seems pretty comfortable with having a threesome with another man, and some lyrics in some of his songs could be interpreted to be about gay sex. Finally, he flirts with Aaron and winks before he goes on stage for the concert.
Moral Event Horizon: Sergio Roma crosses this when he tries to get Aaron Green to give Aldous painkillers for his broken arm, rather than cancelling the concert and getting him proper medical attention.
