Question: Maybe I was dreaming during the mid-'80s, but I'm pretty sure I remember Jeff Conaway on an ABC medieval fantasy show. It was kind of tongue-in-cheek, and he had this hilarious sidekick. I can't remember the name of the show or anything else about it, and my family has been of no help whatsoever. Can you remember it?
Televisionary: Can I? Why, I lived for that show!
Okay, not really but I thought I'd briefly entertain you with the fantasy that you'd found a kindred spirit. But speaking of fantasy, the flash-in-the-pan series in question is Wizards and Warriors, which actually ran on CBS.
As you say, Mr. Conaway (cabbie Bobby Wheeler on Taxi) played Prince Erik Greystone on the adventure-comedy, which revolved around the fictional kingdom of Camarand. Princess Ariel (Newhart and Designing Women's Julia Duffy), daughter of rulers King Baaldorf (Tom Hill) and Queen Lattinia (Julie Payne), was engaged to Erik, who spent much of his time defending the land from the dastardly Prince Dirk Blackpool (Duncan Regehr) and his dark-magic using cohorts Witch Bethel (Randi Brooks) and Wizard Vector (Clive Revill). Aiding Erik in these endeavors was the beefy Marko (Walter Olkewicz), whom I believe was the guy you found so funny. Also along for the ride were the evil Blackpool's bro, Geoffrey (Tim Dunigan), and Erik's brother, Justin (Jay Kerr).
No amount of magic could save the show, however. It debuted in late February 1983 and was banished from the network kingdom by mid-May.
