Trivia: When Mysto the Magician tries to impress the Great Poochini with his audition, he ends with a quick dance. This is a reference to another Tex Avery cartoon, "Doggone Tired", in which the hunting dog did the same dance with background music after finding a rabbit hole.
Trivia: During the show, there is a hair that gets caught in the projector that is removed by Poochini before continuing his performance. The joke was so realistic that many projectionists attempted to remove the hair themselves, not realising that it was part of the cartoon.
When Poochini is rehearsing, Mysto the Magician knocks on the door of his dressing room. At this point, you can see that the handle is on the left hand side of the door, but when Poochini opens the door, he opens it from the right hand side.
