Babies with beards. Once there was a secret orphanage of bearded babies in Holland, and the Brothers Grimm based "Snow White and the Seven Dwarves" on that, which Disney consequentially stole from them, after which some cartoon porno (not hentai, necessarily) stole that version and made it pervy.
Girls can have the deformity too.
And the worst part of it is: You can't shave it off. EVER.
Drunk 17 year old pregnant: Is it a boy?
Doctor: It's a girl.
Drunker 35 year old husband/father: It's a midgetman!
Dr: No, it's a Beard Baby.
D17YPG (nuzzling her baby's chin to her cheek): mmmmmm... Fuzzy...
BEARD BABIES CAN ALSO BE USED TO CATAPAULT AT FRENCHMEN AND BEANERS.
