Watch Orphans' Benefit (1941) Official Trailer

Mickey and friends put on a revue for the orphans. Donald recites nursery rhymes, but the orphans torment him. Horace, Goofy, and Clarabelle do a dance number. Donald tries again. Clara clucks a song while Mickey plays piano (with support from an unseen orchestra). Donald returns, and the orphans finally send a parade of bricks and eggs on balloons over him and use slingshots to drop them on his head.
