The Bullwinkle Show - Season 2 - Eps 159: Peabody's Improbable History - Christopher Columbus
Mr. Peabody and Sherman help Christopher Columbus discover that the earth is round. TRIVIA: It is a popular misconception that Columbus discovered America or that the Earth was round. The Earth’s shape had been common knowledge for centuries and Columbus was actually a terrible person who nearly drove the Caribbean natives to extinction. Also, Columbus was the first European contact with the Caribbean, Central America, and South America - not North America as this episode suggests.
