Magical Maestro is a 1952 American animated short comedy film directed by Tex Avery and produced by Fred Quimby for Metro-Goldwyn-Mayer. It features the Great Poochini (played by Butch Dog), a canine opera singer who spurns a magician. The magician is able to replace Poochini's normal conductor prior to the show through disguise. In 1993, Magical Maestro was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant", making it the only Tex Avery cartoon so far to be inducted.
Mysto the Magician appeals to a snobbish opera singer, the Great Poochini (a pun on opera composer Giacomo Puccini), to let him perform an opening act at the show that night. Mysto's tricks primarily come from his magic wand, which can summon flowers and rabbits. After Mysto dances and asks him if he gets the job, Poochini emphatically says "NO!" as he kicks Mysto out the door into the alley.
