Mississauga Mayor Hazel McCallion has a third arm. That must be the case or this picture of her and her son Peter was Photoshopped, and the Toronto Star wouldn't do such a thing.
If you click over to that same article now, you'll see the Toronto Star has cropped the photo of Hazel and Peter so as to remove McCallion's third arm.
The plot thickens... Thanks to PhotoshopDisasters for the tip.
