Hello Pop!

A theater producer (Healy) is trying to stage an elaborate musical revue. His efforts are constantly interrupted by demanding back stage personalities: a flaky musician (Henry Armetta), a woman who keeps try to ask him something (Bonnie Bonnell), and his raucous sons (the Stooges in children's costumes).
He is able to get the show ready for presentation, but during the main number, the Three Stooges slip beneath the enormous hoopskirt costume worn by the leading vocalist. They emerge on stage during the performance, ruining the show.
