If you see an ugly dude walking down the street you'd best move to the other side as fast as you can.

"We find that unattractive individuals commit more crime in comparison to average-looking ones, and very attractive individuals commit less crime in comparison to those who are average-looking," claim Naci Mocan of the University of Colorado and Erdal Tekin of Georgia State University.

So says a study that was reported on the Washington Post details

"Mocan and Tekin aren't sure why criminals tend to be ugly. Other studies have shown that unattractive men and women are less likely to be hired, and that they earn less money, than the better-looking. Such inferior circumstances may steer some to crime, Mocan and Tekin suggest. They also report that more attractive students have better grades and more polished social skills, which means they graduate with a greater chance of staying out of trouble."
