I have all three sets from this "trilogy" on DVD, Wacky Races, Perils of Penelope Pitstop and Dastardly and Muttley (also known as Stop the Pigeon). My favorite is Dastardly because that's the show I saw more often growing up.
This is the show that started it all though. I like both it and Perils just fine, proving I do like cartoons without superheroes in them occasionally. I doubt we'll ever get an episode guide for this or the other shows in the 'zine, but one never knows. Dastardly is a great villain though.
