When Erica Goldberg returns to apologize to the model UN, the flag for South Africa is incorrect. It should be the old 1928-94 flag not the New South African flag which was only adopted in 1994.
When Murray and Adam visit the video store, there is a cardboard stand-up of C3PO and R2D2 from the 2008 CGI film and TV series.
When Adam and his father, Murray, go to the video store, there is a cutout of C3PO & R2D2 in the background of a few shots (most notable when they're at the counter talking to the clerk). However, this cut out portrays the characters as seen in the animated Star Wars: The Clone Wars, not the original trilogy movies from the time this show is set.
In this episode Production Designer Cory Lorenzen selected a C-3PO and R2-D2 cardboard standee for a video store interior, but the one chosen was from the 2008 McDonald's tie-in of The Clone Wars theatrical preview, and the ephemera was notable and documented at the time for being the first time that McDonald's was finally able to be making Star Wars tie-ins available as a promotion.
