(No attempt is made to explain why seven of the human characters are played by puppets while the other three are played by actual humans.) However, the show includes a considerable amount of profanity in the dialogue as well as including intercourse with puppets.In addition, the show addresses adult themes that are inappropriate for younger children, such as racism, pornography, and schadenfreude.Brian, the café's MC, does his raunchy stand-up act ("I'm Not Wearing Underwear Today").
Kate dreams of starting a "Monstersori" school for young "people of fur".
Three of the puppet characters are direct recognizable parodies of classic Sesame Street puppets: Roommates Rod and Nicky are a riff on Bert and Ernie, while Trekkie Monster bears the distinctive voice and disposition of Cookie Monster, though not his obsession with baked goods.
(The production officially disclaims any connection with either Sesame Workshop or The Jim Henson Company.) All of the characters (puppet and human) are young adults who face real-world adult problems with uncertainty of how they will solve these dilemmas, as opposed to the simplistic problems and invariably happy resolutions faced by characters on children's television programming.
The show draws inspiration from and imitates the format of children's educational television shows, specifically Sesame Street and The Muppets.
Marx interned at the program early in his career, and all four of the original cast's principal puppeteers—John Tartaglia, Stephanie D'Abruzzo, Jennifer Barnhart and Rick Lyon—were Sesame Street performers (D'Abruzzo returned to Sesame Street after leaving Avenue Q).
