Zonker: You really bake marijuana brownies for AIDS patients, Cornell? Cornell: Yup. At least I did until I lost my source. Zonker: But isn't it illegal? Cornell: Of course it's illegal. But not to help suffering people would be immoral. Sometimes you have to answer to a higher law! Zonker: Um... Cornell: What? Zonker: Well, I don't mean to brag, but I've always answered to a higher law. Cornell: I know you have, man. That's what made me think of you!
