Tearjerker's appalling and weepy opus about a retarded Jewish boy living in an attic during WWII not only recalls The Diary of Anne Frank, but also an oblique reference to the infamous never-released surreal weeper The Day the Clown Cried, starring Jerry Lewis as a clown who entertains Jewish children in a Nazi death camp.
Greg and Terry's outfits are an homage to The Beatles in Sgt. Pepper's Lonely Hearts Club Band.
Roger attempts an escape in a tear-shaped escape pod and the mountain face is shaped like Roger, just like Dr. Evil in the Austin Powers series.
When Johnny Depp is being taken off to the spa by Mani and Pedi, Pedi makes a remark that he's going to "try and touch Gilbert's Grapes" a reference to the Depp film What's Eating Gilbert Grape?.
When Mani and Pedi run after Stan and shock against a post because they were holding hands, it possibly refers to the The Adventures of Tintin's comic book The Black Island, when Thomson and Thompson shock against a post because they were handcuffed to each other.
When Stan meets Matthew McConaughey, the actor is playing bongo drums. This is a nod to McConaughey's 1999 arrest for disturbing the peace by playing bongo drums.

The DVD commentary for this episode reveals the ending scene, Tearjerker's burned hand is an homage to the 1980 movie, Flash Gordon.
