The Bullwinkle Show – S01 E20 : Jet Fuel Formula (8) - The Submarine Squirrel or 20,000 Leagues Beneath the Sea

S. Navy, until quick-witted Rocky uses the smoke from the aircraft fire to spell out the phrase "U. S. Taxpayer" and, of course, the Navy needs every one of those that it can get. Soon Rocky finds Bullwinkle, and just as our heroes are about to leave with the moon men, a grateful U. S. government responds by arresting them!
