Dr. Simpson

Dr. Simpson, the chief of complicated surgeries at the invasive care unit, first seen in "Lisa the Simpson". In the episode, Homer is devastated when he can't find any successful Simpson men to prove to Lisa that there is no genetic condition causing intelligence deterioration. As a last ditch effort, he grabs Dr. Simpson, who explains that the defective Simpson gene is only on the Y Chromosone. She makes a brief cameo appearance in "Catch 'em If You Can".
