Leaning, Lobsters and Lectures - S1-E11
Continuity mistake: Buddy is doing a lobster themed cake for a bachelor party. When Buddy goes in to tell the staff, there is a huge cake 3 tiers high being worked on, almost complete, on the table in the background. As he makes the parts for the lobster cake the cake in the back has fewer tiers, no decorations, no icing, and back again, completely out of order.
