Muppet Cowboy X--anyone else seen him? Sometime in the late 80s/early 90s, I distinctly recall Cowboy X appearing as a Large Lavender Live Hands puppet, along with a separate Cowboy O Muppet who looked similar except for the letter on his hat. The plot of their episode centered on a dispute: each cowboy wanted to tag everything on Sesame Street with his trademark, much as the original cartoon vandal did. One of the adult humans (Susan or Maria, I think) ended the dispute by teaching the cowboys to cooperate; they could each mark an X or an O by playing tic-tac-toe on a huge piece of paper. (In fact, I could swear Elmo piped up with "Tic-tac-toe!" when the sponsors were announced offscreen at the end...) Does anyone else remember this episode, especially other details of the cowboy characters?
