7x10 - Ace of Cakes

This week Erika is tasked with creating an extravagant, 5-cakes-in-1 anniversary cake for Philadelphia's famed Mummers Parade, only to have gravity rain on her parade as full-blown cake-meltdown strikes. Duff is asked to throw out the first pitch at an Orioles game but has to be taught how to throw a ball first. And in a bakery first, Charm City Cakes is challenged to a duel by one of their clients. Will Geof be able to defend the bakery's honor?
