Archbishop Vincenzo Paglia embraces students before sampling milkshakes during a news conference to pick a milkshake for the upcoming World Meeting of Families, Monday, March 9, 2015, at a Potbelly Sandwich Shop in Philadelphia. Paglia met with about a dozen students at the shop in downtown Philadelphia to pick the milkshake that would benefit planning efforts for September's event. Paglia, the president of the council in charge of the event, settled on the flavor "#PopeInPhilly." Pope Francis will attend the closing event Sept. 26 of the world meeting. The next day he'll celebrate an outdoor Mass. Fifty cents from every shake sold at three locations will benefit planning for the events. (AP Photo/Matt Rourke), APTOPIX
