Cartoons are often filled with "in" jokes, even a classic like 1933's "THREE LITTLE PIGS!" Each pig has a house made of unique materials (straw, sticks, and bricks). But hey, even piggies have to accessorize! As Andy Rooney would say, "didja ever notice..." While there's a sentimental picture of "Mother" (awww....), ya gotta love the picture of Uncle Otto (a football - pigskin!), Father (sausages), even Hawaiian pinup-pigs in Hula skirts!
