I grew up watching these and met Okefenokee Joe as he would come to our school with snakes and what not. Okefenokee Joe's PBS educational movies are ripe for the riffing. The link is below;

He sang on them about swampy the dog and sketter the cat who got eaten by an alligator so he replaced him with another cat and called him sketter. He always talked about being swampwise too, lol. Still makes me laugh almost 33 years later.

Love your work past and present. I grew up watching Joel and the bots and went to high school during the Mike years on MST3k. And you guys were a god send on Turkey day, lol. All the Best!
