The "Ice Bucket Challenge" has become a viral sensation, raising money and awareness for the ALS Association. Lots of celebrities have gotten in on the action, which provides the perfect excuse to show of those impressive bodies. Here's just sampling of the videos starring Emblem3, Arrow stars Stephen Amell & John Barrowman, Jesse Metcalfe, Chris Pratt & Teen Wolf's Tyler Hoechlin. I think it's time for some porn stars to join in and raise some money for this great cause.
