Hot Cross Bunny

In the Bugs Bunny short "Hot Cross Bunny", Bugs is "Experimental Rabbit #46" in the Paul Revere Foundation (which sports the unlikely slogan 'Hardly a man is still alive'). Bugs is seen living a somewhat pampered life, oblivious to the fact that a scientist plans on switching his brain with that of a chicken. The scientist brings Bugs out to the operating table, in front of an audience of fellow doctors. Bugs, of course, thinks he's been brought out to perform. He pulls out all the stops, singing, dancing, scatting, comedy routines, magic acts. Upon finishing each act, he looks around to see the stern-faced doctors in the exact same frame position each time. The scientist attempts to retrieve Bugs but is usually pushed away. He finally succeeds as Bugs is in the middle of a scat routine. Bugs manages to escape and a chase ensues. Finally, Bugs is knocked out and placed on the table. But at the last minute, He switches the electrodes and the scientist ends up clucking like a chicken, while the chicken states in plain English his hope that the experiment can be reversed.
