The counselor's office in the first high school was the only room that did not actually exist in the first high school that 'Dizzy/ Gil' attends. The office was constructed in the foyer of the high school due to space constraints in the actual administrative offices of the existing high school.
Kirk advises Dizzy that a girl will "powerlevel" him, as though it were a beat-down. "Powerlevel" actually refers to a concept in Kirk's beloved EverQuest wherein a higher-level character protects and/or enhances a lower-level character in order to help the lower-level character "level-up" at a faster rate. It is actually something desirable. Ironically, The New Guy and EverQuest were developed by the same company.
What are the differences between the Theatrical Version and the Director's Cut?
The Director's cut of "The New Guy" has only been released in the US so far. It contains some cuts for the PG-13 and also two new plot scenes which feature DJ Qualls as William Wallace (not Patton) already in the first football game. A detailed comparison between both versions with pictures can be found here.
