S7, E3: Larry is dead set against filming a `Seinfeld' reunion and is about to tell Jeff and NBC that he won't do it when he bumps into Cheryl. She tells him she's just got back into acting and encourages him to write a part for her. Realising that this might win Cheryl back, Larry convinces Jerry Seinfeld, Jason Alexander, Julia Louis-Dreyfus and Michael Richards to come together for the reunion show.
