The Bullwinkle Show (1959)

Season 1: Episode 51

Tricked by a fake lifeboat drill called by Boris Badenov, that dastardly USC graduate (that is, the Ukrainian Safecracking College, dollink), into a leaky lifeboat—Moose overboard!—our heroes are all at sea and lost in a fog. But little does Boris know that Moose and Squirrel have courteously taken along that old and taciturn (and red and green and spotted) gentleman, Uncle Chumley, who bears an uncanny resemblance to a certain mooseberry bush.
