S2E12 The Masquerade Ball

Fred purchases tickets for a fancy costume ball from his boss, Mr. Rockhead. He hopes to impress his supervisor while dressed up, but things take a turn when Rockhead changes his outfit. Instead of being the target of Fred's flattery, he inadvertently becomes involved in Fred's plan, completely unaware of the scheme unfolding around him.
