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. While I'm completely skeptical of its ability to predict with any degree of reliability (I will not be fielding questions as to its accuracy), I'd be lying if I didn't giggle when confronted with "Shake to calculate." In related news, I am twelve years old.

Once you've got your prediction, though, there's even more fun to be had. Entertaining facts from scientific studies, comparisons to populations from other countries. Heck, you can even share with your friends. How delightful! Hey everyone on Twitter! I have some information you might be interested in! There's a huge list of ready-made status to choose from, so have a ball.

The video is even better. Please do yourself a favor and watch it. While there is almost certainly some handy information in there (turns out size might not actually matter!), it is worth two minutes of your time to find out which of the people depicted is huge in Greenland.

This app is only intended for humorous purposes. It also accomplishes its goal.
