Trivia: Ugly Americans

  • Actor Allusion: Michael-Leon Wooley, the voice of Twayne, once provided the voice for Audry II, the man-eating plant from Little Shop Of Horrors on Broadway. In the episode Little Ship of Horrors there is a species of plant people resembling Audrey II running a flower shop. Wooley provided the voice of the shop owner.
  • Hey, It's That Voice!: Kong is Ken Parcell.
    • Natasha Leggero, the voice of Callie, was a 2010 Last Comic Standing judge (Leggero was also the replacement voice of Ethyl on Comedy Central's Brickleberry), while Randall's voice actor Kurt Metzger was a contestant (and even won best joke of the season). Both also later ended up on Comedy Central's 2010 Hot List.
    • After her sex change in "Mark Loves Dick", Callie's voice changes into H. Jon Benjamin.
    • At least three Saturday Night Live cast members have done voicework on this show: Kate McKinnon (who appeared on the show before she joined SNL), Bill Hader, and Kristen Wiig.
  • Name's the Same: One of the characters on this show is named Frank Grimes. It's not the same one who was angry at Homer for living a cushy life (despite being a total idiot) and ends up having a Villainous Breakdown and electrocuting himself after Homer enters and wins a nuclear plant design contest for children. Justified as David M. Stern (a former writer and story consultant for The Simpsons) worked on this show.
