Elmer is mixing chemicals in his little junior chemistry set "trying to make a normal character into a devilish fiend." We then see his head change in shape to a devil-like one with pointed ears. (I always suspected Fudd was a sadistic, evil punk!)

The first clever gag involves a test tube with his solution and the wild colors it turns, including plaid and barbershop rings, etc. "Rover," his experimental dog, must drink the stuff. Rover is chained up so bad this would have animal-right activists on his back in no time today. Fudd forces the liquid down the dog's throat. (Man, is this guy plain evil or what?)

When the dog freaks out and smashes through the front window and runs away, Elmer goes looking for another experimental animal. Who-know-who winds up (voluntarily) in his laboratory. And.....you know who turns the tables? Along the way, we get two cases of mistaken identity, and that turns out to be the big joke of the cartoon.

I enjoyed Bugs' line referring to the Spencer Tracy film version of "Dr. Jekyll and Mr. Hyde."

Overall, this is "fair," clever in the one "identity" gag but annoying at times, too, with Fudd's abrasive and stupid laugh and carrying-on.
