Upside Down World

Sung by Ernie and Bert in Follow That Bird. They sing it when they find Big Bird, and when trying to get Big Bird's attention, Ernie turns the plane he's piloting upside down, and instead of trying harder to get Big Bird to know that they are there, Ernie starts singing, to Bert's annoyance. Halfway through the song, Bert's bottlecap collection falls out of the plane and falls on Big Bird, who thinks that it came from a hailstorm. When Bert finally starts singing and having fun with the song, Ernie realizes that Big Bird is gone, and blames Bert for losing Big Bird.
