Creators Brian Robbins and Dan Schneider both starred on ABC's "Head of the Class" (1986). The longest running cast member (apart from Kevin Kopelow) as of April 2005 was Josh Server, who was on the show from the beginning until the full cast change. For the show's 100th episode in 1999, Britney Spears and Busta Rhymes were scheduled to perform. Spears had to cancel due to a knee injury, and Lauryn Hill filled her spot.
