An old teacher of mine actually had a student named... Placenta.
For anyone who doesn't know what that is, here is the definition from dictionary.com:
A membranous vascular organ that develops in female mammals during pregnancy, lining the uterine wall and partially enveloping the fetus, to which it is attached by the umbilical cord. Following birth, the placenta is expelled.
The mother named her that because it "sounded pretty". That's the worst.
