Foghorn Leghorn is sound asleep when the barnyard dog places an ostrich egg beside him for a gag. When Foghorn awakes and sees the egg, he thinks he's its mother! The egg hatches to reveal an easily embarrassed baby ostrich that Foghorn regards as his son. The dog insults the ostrich repeatedly, causing him to bury his head in the ground. So, to protect his son's honor, Foghorn challenges the dog to a boxing match.
