The poster in Murray's office at the consulate says "It's not boring in New Zealand"
When Jemaine says "man's feet, Bret" whilst in the dumpster, his lips don't move.
When Bret searches in Mel's backpack for styling gel, he takes out Mel's CD player from the backpack twice, most likely an editing error.
Editing Goof: When it first shows Jemaine and Bret performing as Simon and Garfunkel, Jemaine's hands are behind his back and in the next shot he has one hand in front of his chest.
Goof - During the scene where the real Art Garfunkel shows up, Karen's head is visible in a close up of Jermaine before she actually shows up in the scene.
Although credited, Kristen Schaal (Mel) does not appear in this episode.
Murray mentions having served in the New Zealand army. Rhys Darby himself served three years in the New Zealand army, from 1991-1994.
For at least one second, you can see the shadow of a boom mic in lower right corner of the first shot of the first scene with Mel riding to catch up to Bret and Jemaine on bicycles about 4 minutes into the episode.
The poster in Murray's office reads "New Zealand - better than Old Zealand".
Bret and Dave confuse a bunch of rappers including Mos Def, Ice Cube, Method Man and Snoop Dogg for appearing on Law and Order: Special Victims Unit. The actual actor they are thinking of is Tracy Marrow (known as Ice-T in the music world).
