Quote from Kramer in The Parking Space
Mother: [to Kramer] Boy, I don't know about your friend, Jerry. He says some pretty stupid things sometimes. Kramer: Oh, congratulations. Mother: What for? Kramer: Well, you're pregnant. Mother: What? Kramer: You're not pregnant? Mother: No, I'm not pregnant. Kramer: Are you sure you're not pregnant? Mother: Yes, I'm sure! Kramer: That's weird.
