- "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 died 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, as seen in A Taste of Freedom.
