Mickey's Amateurs is a Mickey Mouse short released 17 April 1937.
Mickey Mouse is hosting an amateur radio talent show in front of a live audience. He terminates unworthy performances by ringing a gong. First, Mickey's gong ends Pete's rendition of "Asleep in the Deep".
Next, Mickey introduces Donald Duck. He gives Mickey an apple, perhaps to curry favor, but his recitation of "Twinkle, Twinkle, Little Star" ends badly as he forgets the words. Mickey rings the gong, and Donald is removed from the stage. Just as Mickey is announcing the next act, a disgruntled Donald returns to take back the apple.
The next act is "the two Claras: Cluck and Belle." Clara Cluck sings a clucking version of "Il Bacio", a waltz by Luigi Arditi, accompanied by Clarabelle Cow on piano. Despite several blunders, the performance is the first to avoid the gong.
Next, Donald returns to the stage uninvited, wearing a disguise and carrying a violin case. Upon reaching center stage, Donald throws off the disguise and pulls a submachine gun from the case. He holds Mickey and the audience at gunpoint, determined to finish his recitation, but again he forgets the words. When the audience laughs at him, he opens fire. Donald is quickly removed from the stage.
For the show's final act, Mickey introduces Goofy and his "fifty-piece band," which turns out to be a multi-instrumental device on wheels. Goofy begins with "In the Good Old Summertime" and moves on to "There'll Be a Hot Time in the Old Town Tonight", but the tempo and intensity of the song causes the machine to explode. Goofy appears out of the wreckage and sheepishly says, "It busted!" Donald breaks out of Goofy's bandmaster hat and quickly recites a word-perfect recitation of "Twinkle, Twinkle, Little Star", satisfying his victory. However, the "iris" closes around his neck. He struggles with it, but it finally closes.
