In page Milton Berle:

"

As a guest star on The Muppet Show,[3] Berle was memorably upstaged by the heckling theater critics Statler and Waldorf.[4] The Statler and Waldorf puppets were inspired by a character named Sidney Spritzer, played by comedian Irving Benson, who regularly heckled Berle from a box seat during episodes of the 1960s ABC series. Milton Berle also made a cameo appearance in The Muppet Movie as a used car dealer, taking Fozzie Bear's 1951 Studebaker in trade for a station wagon.[citation needed]
