Shaggy-haired Sam Sheepdog bids a good morning to his coworker Ralph and punches the clock. Ralph Wolf returns the greeting and punches in as well. The two exchange pleasantries but when the whistle blows, they go straight to work: a full eight-hour day of outrageous cartoon violence as Ralph attempts to steal sheep from Sam's flock and Sam attempts (and seemingly always is able) to thwart Ralph's efforts. First appearing in 1953's Don't Give Up the Sheep, the Warner Bros. duo have starred in another half-dozen cartoon shorts since then, with a unique appeal that seems to span multiple generations.
