Quote from Esther Clavin in Heeeeere's... Cliffy!
Esther Clavin: Norman, I want to thank you. Norm: For what? Esther Clavin: Well, I know Clifford doesn't have many friends. I remember that surprise birthday party I organized for him and you were the only one who showed up. Norm: Yeah. Where were you, anyway? Esther Clavin: I just forgot.
