Mannie Davis (1945)
Ants in Your Pants is a 1945 animated cartoon from Terrytoons featuring what they are most notorious for: cycles! And cycles of the commonest kind: ants harvesting and a baby factory! It also has a voluptuous Queen Ant and a sweetly delivered punchline which may make it worth your trouble. Withheld from television release; presumably because it leaves too many “birds-and-bees” questions unanswered for tiny tots (and their beleaguered parents).
