I truly love iPhoto's face recognition feature, which enables to me to search for photos based on people, not events nor the chronological order. However, today I found a slight bizarre iPhoto faces freak out. I was searching for photos from my father. Age 62, white hair. He has a pretty unique appearance as you can see on the picture. In the learning process you often get false positives. 

However, look at the two other suggestions iPhoto gives me.
