How to Be Charitable In Your Underwear (Photos)

Cupid's Undie Run is a four-hour party with a mile(ish) fun run in the middle. No, they’re not crazy, they’re just crazy serious about raising money for the Children's Tumor Foundation. Cupid’s Undie Run started with the goal of raising money to end neurofibromatosis, and having raised $3.5 million last year, this thing just keeps getting bigger. This event was held Saturday in Seattle, and our man in the great Northwest, Matt Baume, photographed for us. Enjoy the pictures of men and women in their underwear here, and maybe be inspired yourself to participate in an event near you.
