Each episode begins with Bert and Ernie climbing into their beds for a night's sleep. Suddenly, Bert's bed starts shaking and tapping, and Ernie hops aboard as the bed flies out of their apartment and into their next great adventure. Each adventure has Bert and Ernie in a new location and a new situation. Sometimes they're accompanied by Bert's trusted pigeon-friend Bernice, or Ernie's toy Rubber Duckie. Often they encounter new and old friends, and also adversaries, along the way. (http://en.wikipedia.org/wiki/Bert_and_Ernie%27s_Great_Adventures)
