It’s weird. Both Star Wars and Star Trek fans shun and ignore this. They treat it like the Star Wars Holiday Special, or Star Trek: The Animated Series, and pretend it never happened.
Personally, I consider it canon in both universes:
[The Carbonite Maneuver (1985)] (Viewer #82,684)
If it doesn’t have Harvey Corman flirting with Bea Arthur in the Tatooine cantina, it’s not really Star Wars.
Ingrates…they seem to have forgotten this classic also. https://www.youtube.com/watch?v=fjniNHX92qg
