 FACT: Many of the staff claim to be huge Muppets fans, yet they have  trouble distinguishing between the Muppets and Sesame Street. Its  obvious that Abby appears on Sesame Street (as the skit involves  Elmo and Big Bird), yet they continually refer to the show as  "Muppets" (even despite Abby lecturing Debbie about the difference  between the two). Further, this episode was set in 2004, several  years after "Muppets Tonight" ceased production.
