The colossal dodgeball event is expected to pin at least 400 against 400 in all-out rubber-ball mayhem to raise money for Life Unchained, a social nonprofit organization that provides seed money to local start-up nonprofits and dream projects. Registration will begin at 10 a.m., followed by the first fated volley at 12:30 p.m. The action will last until the final player standing on either team gets hit with a dodgeball or an insatiable craving for pancakes. After the ball-slinging massacre ends, participants can revel in food and drink specials at the AT&T Pavilion after party and compare bruises forming in the shape of badges of honor. Each participant will receive a free T-shirt and ticket to the Philadelphia Wings lacrosse game later that night; guests are encouraged to tailgate until the Wings take flight at 7 p.m. The last survivor on the losing dodgeball team will secure a coveted luxury weekend stay at the Loews Hotel, and 10 players from the winning team will be selected via raffle to win $100 in prizes.
