- The Justice Friends segments feature a fictional television show called "Puppet Pals" which star Mitch and Clem, a Punch and Judy-esque puppet duo who visually resemble Ernie and Bert and stand behind a Sesame Street brick wall. Outside of Justice Friends, the Puppet Pals were also seen in live-action form in short segments that have appeared in several episodes. They've also made cameos on The Powerpuff Girls, notably in the season one episode "Mommy Fearest."
