Birth of a Notion (1947)

Daffy Duck, determined to dodge the long migration south, schemes his way into staying put by hunting for an easy mark. His search lands him at the doorstep of a wacky scientist and his loyal, slobbering dog, Leopold. What starts as a clever con quickly spirals into chaos, as Daffy finds himself trapped in a house full of eccentric experiments and a pooch who won’t leave him alone.
