Of course the ultimate metacinematic mindbender by the Master is "Duck-a-Muck", in which poor Daffy Duck finds himself trapped in an animated world where the rules, props, backgrounds, seasons, and even the film's registration in its supposed projector gate keep being redrawn, and it is impossible to accommodate to the metamorphoses. In the end the exasperated Daffy cries out like the Biblical Job before him "Who is responsible for this? I demand that you show yourself!" Then it's revealed that the mischievous Animator of Daffy's cruelly surreal world has all along been Bugs ("Ain' I a stinker?") Bunny.
