Prize Cow, Pop Tarts and Patience Cake Boss : Season 4 Episode 22

The bakers make a cake for a dairy farmer's prize cow; not only do they make it life-size, Buddy also has it set up so it can be milked. Also, Buddy makes a cake for a boy whose family recently moved to Hoboken, with the cake being mostly made of Pop Tarts. Later, Joey, still having trouble on deciding between his firefighter or baker careers, asks Grace for advice.
