 The pilot has been seen in two versions. The original version that was shown  on 12 May 1979 had an extra scene toward the end where Moose suggests the  viewers should call their local TV stations, to tell them how much they liked  the show (so it could possibly be made into a series).  Versions seen since  (including the version shown at the Slimecon convention in 2002, and the  version in collectors circles) are missing this dialouge.
