Acrobatty Bunny (1946)
The show/video is a collections of 7 cartoon shorts edited together without any introductions other than the original titles.
The "Pinocchio" gag is recycled from this cartoon.
When Bugs comes out of the dressing room dressed as a clown, he is singing "Laugh, Clown, Laugh." This is a spoof of Simon telling Tito (Lon Chaney) the same in the 1928 silent film, Laugh, Clown, Laugh.
