When Carly grabs Nora's arm through the slot and pulls her face against the glass, Nora growls in a weird voice "Release me!", a reference to a scene in Independence Day.
The plot is a spoof from Misery as Carly, Sam and Freddie (celebrity web show hosts) get trapped by their psycho number one fan. Also, it is indicated that Nora owns a pet chicken, as Annie owns pet pig.
