Starts out fairly good with some good running gags, but about a third of the way into the story, it just lost steam and became silly. A few of the songs would have been good if they'd been sung by people instead of Muppet voices. Several stars made cameos — Edgar Bergen, Milton Berle, Mel Brooks, James Coburn, Dom DeLuise, Elliott Gould, Bob Hope, Madeline Kahn, Carol Kane (who had one of the funny bits — when ever someone would say something false about frogs, Kermit would say "MYTH," and Carol would pop out from behind the scenery and say, "Yes?:), Cloris Leachman, and Steve Martin.
