The hour long Canadian version of this episode exists.
Eventually the 1981 episodes were removed from rotation after 1987. Nickelodeon did not want to renew the lease on these episodes since these episodes dealt with more mature teen topics.
The hour-long version of the episode exsists, but the Billy Joel clip in the episode was taken from an episode of Saturday Night Live.
Many cast memebers did not make it beyond the 1981 season. Among the cast members are Kevin Somers, Mike Lyon, Rodney Helal, and Kevin Schenk.
