The lice list: Steven Applebaum, Joannie Asper, Patricia Bucci, Reggie Cameron, David Entwhite, Leon Griffin, Courtney Gripling. Note that three of them (Steven, Leon, and Courtney) are in the same homeroom.
Carl and Hoodsey attend Lucky Elementary School - not a particularly surprising name, when you consider it's pretty much right next to Lucky Junior High School (as seen in "Dare I, Darren?").
This is the second time we see Hoodsey's hair.
Dodie wears her hair in different hair styles, such as a bun or loose hair, in this episode.
This is the first time we see a major argument between Dodie & Ginger.
In "Stealing First", Ginger is in a different homeroom from Dodie and Macie, but in this episode, they're in the same one (along with Darren, Courtney, Miranda, and Mipsy).
