The answer to the question: Who needs to show that he can be a worthy father? is inside the article: A newspaper story in the Barnyard News predicts a cold winter. To avoid freezing in his shack, Foghorn decides to woo Miss Prissy ("I need your love to keep me warm"), who lives in a warm, cozy cottage across the way. Miss Prissy is flattered by Foghorn's two-second courtship but tells him that, to prove his worthiness as her mate, he needs to show that he can be a worthy father to her bookish-looking son. The little boy – Egghead Jr., a chick similar in appearance to Tweety, dressed in a stocking cap and oversized glasses – would rather read about "Splitting the Fourth Dimension" than engage in typical little boy games. Foghorn immediately catches on to this and sets out to win his audition by showing Egghead Jr. how to play various sports games. Although he apparently has never participated in any of the below-listed events before, Egghead Jr. effortly masters them all, as depicted in the cartoon's gags:  Baseball. After Egghead Jr. swallows the ball whole and clonks Foghorn over the head with the bat causing Foghorn to yell "NO! NO, boy! You're supposed to hit the ball with it! The ball!" the rooster has Egghead Jr. properly use both items. Egghead goes to bat and smashes a line drive down Foghorn's throat, and later fires a fast-pitch offering that slices through Foghorn's bat and a row of trees in the grove. When asked to explain, Egghead produces a series of scientific formulas. Making paper airplanes. Foghorn makes a conventional one, but Egghead Jr. creates a fighter that not only floats sleekly through the air, it shoots Foggy's plane down in flames. Foghorn is handed another scientific explanation, but Foghorn rejects., can you guess it ?
Answer:
Foghorn
