Excuse me, your underpants are showing. That was the idea on a brisk October morning in Winfrey Point, where runners gathered for the 2012 Dallas Undy 5000. Created by the Colon Cancer Alliance, the 5K run encourages runners to showcase their whimsical underpants as they run. Photographer Stephen Masker was on hand to capture the best undies.
