2x3 - The Muppet Show

Fozzie Bear is so intimidated by the thought of meeting Milton Berle, "the King of Comics," that he spends the whole show hiding from the guest star. His flimsy disguises don't fool Kermit or Scooter, but when Fozzie finally overhears Milton saying that he'd like to do a song-and-dance with him, Fozzie springs out of hiding, and the pair performs "Top Banana" together in baggy pants and big shoes.
