I voted two...
but I had a third at one time, then in a mishap with my brother he accidently cut it off.
Well the stabbing wasn't an accident, but the loss of my nipple was. He was stabbing me cause when I threw my NES controller at the TV in anger it bounced and knocked his plate of steak all over the floor and the dog ate it. So he sliced me twice with the steak knife... one was kinda deep. Kinda sucked.
