Laura Moon, 18, of Leeds, England, recently found out that she has an extra pair of kidneys. She's kindly offered to donate her extra pair. From The Guardian:
She only became aware of her unusual anatomy six months ago after undergoing an ultrasound scan to investigate stomach pains following a car crash.
'I realised that the doctor scanning me hadn't said anything for a long time. I thought he was going to give me bad news. But then he said: "You've got four kidneys." He measured them and I have two which are 14cm and two which are 9cm.'
