The stated mission of the Celebrities for Charity is pretty straightforward: "To unite the goodwill of celebrities with the generosity of their fans to assist people in need." Its list of past beneficiaries includes schools, hospices, and cancer foundations. As we learned last week, Rob Gronkowski is nothing if not generous. Which is why he's helping out the only way he knows how: By raffling off the opportunity to party with him at a Bruins game. Oh, and it's called—in all seriousness—the Boston Gronk Party.
