Orphan's Benefit is a Mickey Mouse short released 11 August 1934.
Orphan mice arrive for a free show entitled "Mickey's Big Show: Orphan's Benefit." As they file into the theater they are given free lollipops, ice cream, and balloons.
Donald Duck begins the show by reciting "Mary Had a Little Lamb", and then "Little Boy Blue." But when he says "come blow your horn," an orphan loudly blows his nose to disrupt Donald's performance. He recites it a second time, but this time the orphans blow their noses. Donald loses his temper and challenges them to fight, but is pulled backstage by an off-screen stagehand.
The next act is Goofy, Horace Horsecollar, and Clarabelle Cow performing an acrobatic dance. Horace dances with Clarabelle, and Goofy attempts to pick him up but gets his head stuck. Goofy then throws Clarabelle back to Horace. Horace spins Clarabelle around and throws her in Goofy's direction. Goofy catches her dress and Clarabelle closes out the act by hitting Goofy on the head.
Donald recites "Little Boy Blue" again, but blows his own horn before the orphans can respond. An orphan blows ice cream at Donald to provoke him, and the orphans punch Donald into a daze with their boxing gloves. Then, Donald is once again pulled backstage.
For the next act, Mickey Mouse introduces Clara Cluck, who clucks "Chi mi frena in tal momento" from Act II of Gaetano Donizetti's Lucia di Lammermoor, accompanied by Mickey on piano. When she is unable to reach a high B-Flat note, an orphan fires a slingshot to help finish the song.
During the final act, Donald returns to the stage and quickly recites one line – "Little Boy Blue, come blow your horn" – and waits for the orphans to interrupt him. Yet as they seem well-behaved this time, Donald continues the recitation. But when he says "Where is that boy who looks after the sheep?" the orphans answer in unison "Under the haystack fast asleep, you dope," causing Donald to lose his temper again. The orphans tie bricks, a plant, a fire extinguisher and eggs onto their balloons, float them over his head, and fire their slingshots. After the orphans laugh, Donald accepts defeat and finally closes out the show.
