Stewie comes out of the losing end of a battle of wits with Doug, who gets to sit at a table with the 1st graders. Peter. having been made Susie's Godfather, decides he wants in on the piñata, but when the head waiter tries to stop him he is accidentally hit and interprets Peters insistence that he's the Godfather as being a mobster.
