Archbishop Vincenzo Paglia picked the winning flavor from three choices during a visit Monday to a Potbelly Sandwich Shop. The president of the Vatican department that organizes the world meetings, Paglia got help from a dozen Catholic school students.

The shake features a blend of vanilla ice cream and shortbread cookies.
