- "Sure. You can go to Medical school, IF YOU WANT TO GIVE UP ON BEING A COMEDIAN!"
Sadie is Zoidberg and Norman's adoptive mother. Their mother and father were killed when giving birth to their children because Decapodians die after they are done mating. She often pressured Zoidberg into becoming a doctor, shattering his dreams of becoming a comedian. However when Zoidberg became a doctor she criticized him for giving up on his comedy dream, such as in A Taste of Freedom.
