A doctor did this. Before I get any deeper into this story, I want to point out that a person with the prefix "Dr." in front of his name—Dr. Christopher Culligan, a Canadian ER physician and instructor at the University of Toronto Faculty of Medicine, to be precise—is responsible for this mobile app that promises to infer a man's size based on a variety of factors. This criteria includes but is not limited to height, shoe size, butt size and whether the man is gay or straight. Seriously.
I can't believe I actually get to write these words, but of all the apps I've seen that promise to measure a man's member, this has to be the best.
