Main Characters in this Episode
Cindy Vortex: [assuming a martial-arts stance and shouting back] Bring it, wrinkles!
James Isaac 'Jimmy' Neutron: What is it, Carl?
Carl Wheezer: Jimmy, Sheen is acting weird.
James Isaac 'Jimmy' Neutron: Yeah, Carl where have you been for the past eleven years?
James Isaac 'Jimmy' Neutron: Yeah, so do child stars.
- Goof (continuity error): When Sheen puts his head on his body, he gets it on backwards and it stays like that for awhile, but when Jimmy explains about the alternate dimension to Spamdini, Sheen calls out, "Nap time!" and his head is turned the right way. Afterward, Sheen's head is turned backwards indefinitely.
- Goof (continuity error): "One of Us" starts en medias res with Jimmy & Cindy running away from many townspeople who fell victim to the hypnotic TV show. Here they are shown running in the street, but once the flashback catches up to this spot, they are running on the sidewalk.
- Goof (continuity error): Sheen's hairstyle alternates between shots, especially while acting obnoxious on stage. For example, he yells, "Just pick Betty and get it over with!" and his hair is how it usually looks; then in the following shot it is styled to appear shorter and more flat.
- In "Vanishing Act," the background music for Jimmy's magic production is a version of "Sirius," the introduction to The Alan Parsons Project's 1982 album 'Eye In the Sky'.
