Sean S. Baker, Spencer Chinoy and Dan Milano's fabricated American characters have had an absurdly resilient life span, moving from public access to FOX to IFC to MTV in a variety of incarnations.
I will always be partial to the 2002 FOX sitcom version, which featured Seth Green, Eugene Levy, Sarah Silverman and Bob Gunton as some of the humans working on a magnificently awful children's show called "Sweetknuckle Junction."
FOX didn't quite know how to develop or promote "Greg the Bunny," which was rapidly burnt off in the spring of 2002, but thanks to DVD viewers can still get to know adorably naive Greg, self-destructive and self-involved Warren DeMontague, "Sesame Street"-hating Count Blah and intellectually deficient Tardy Turtle.
The humans aren't bad either. Of all of Seth Green's failed live-action TV ventures, this is the best, while it's worth watching Silverman experiment with her comedic persona.
