Here is the full version of the digital short that was played before Wall-E in theaters.

Dignity. Poise. Mystery. We expect nothing less from the great, turn-of-the-century magician, Presto. But, when Presto forgets to feed his rabbit one too many times, well, there's really no telling what to expect! This latest comical short film from Pixar Animation Studios follows the escalating high jinx of the amazing Presto, his rabbit Alec, and what happens onstage when a star magician's ego provokes some clever revenge from his neglected costar.
