Birth of a Notion is a 1947 Warner Bros. Looney Tunes cartoon directed by Bob Clampett and Robert McKimson.

However, complications arise when confronted with Leopold's master, a scientist fixated on acquiring a duck's wishbone for an experiment.

Ultimately, Daffy departs, but the scientist settles for a dog's wishbone, prompting Leopold's departure as well.

Daffy's attempt at infiltrating another abode is thwarted by a Joe Besser-esque grey duck, resulting in Daffy's inadvertent flight southward, where he discovers Leopold, equipped with a makeshift flying apparatus, accompanying him.

Director Robert McKimson employs his character design of "Barnyard Dawg" to portray Leopold, the canine companion of the mad scientist, with the scientist himself rendered as a caricature, visually and vocally reminiscent of Peter Lorre.
