These Looney Tunes segments are sometimes edited out when the film is rerun these days on cable TV (I know they were edited when this movie ran on cable's Sci-Fi channel).
Just moments ago, I found this on Wikipedia:
"The DVD includes a longer version of the cartoon short. In it, Daffy mistakenly writes the title Gremlins 2 as Gremlin Stew and then attempts to rename the film The Return of Super-Daffy Meets Gremlins 2 Part 6: The Movie. This material was removed from the film because early audiences expected a live-action film and were bewildered by the lengthy animated sequence."
I never knew this! I guess I will have to rent the DVD now.
