Premise: High Noon Toons was a 3-hour programming block of cartoons hosted by two cowboy hand puppets named Haas and Lil' Jo (a Bonanza pun) shown on Cartoon Network in the mid-1990s. The series was made by Matt Thompson and Adam Reed, who later went on to create adult-themed cartoon series such as "Sealab 2021" and "Frisky Dingo" for Adult Swim and "Archer" for FX.
Hypothesis: Cartoon Network first started in 1985.
