S1·E9 Andy's Girlfriend

Andy has a new girlfriend, and Cheryl wants Jim to treat her nicely because not only is she Andy's first girlfriend sine Carrie, but also Ruby's piano teacher. During dinner, Alicia tells Jim she's a vegetarian, and not only that, but also a Peckers fan – a big insult to Jim. Alicia and Andy break up and get back together, but she keeps turning down invitations to have dinner at Jim and Cheryl's. The reason? She doesn't like being around Cheryl. Jim rubs it on her face until Cheryl confronts Alicia, who reveals it's only because she thinks Cheryl's too perfect.
