The Armpit family is one of those strange medical anomalies. Father Eggers and wife Cueball do not contain the hair gene in their DNA. They are perfectly healthy, but neither has even one follicle of hair, and will never grow any.
Their children are son Smoothy, twin daughters Lykoi and Sphynx. None have any hair. And then... there's youngest son Nosey.
Nosey is unique among the Armpits, in that he actually has two hairs each 4 inches long, one sticking out of each nostril, giving the appearance of a very thin mustache, rather startling on a two year old.
Eggers strongly suspects Cueball of having an affair, but nevertheless forgives her, and raises Nosey as his own.
Soooo... I guess technically, the hairiest Armpit is Nosey, but he's still way too young to shave.
Does money really grow on trees?
