Cake Boss S04E12 - Second Anniversary, Surgery and St. Paddy

Buddy undergoes surgery for his hernia; in his absence, he had Mauro take over making the cakes. Mauro's first assignment -- making a second anniversary cake for a gay couple, who previously had their wedding cake made by Buddy (in the first season episode "Weddings, Water and Wacked!"). Also, Buddy was made Grand Marshal of Hoboken's St. Patrick's Day parade; however, Joey was jealous, as Buddy is not Irish.
