Leonard: So now let's bring out theoretical physicist, Dr, Sheldon Cooper.
Sheldon: Hello, female children. Allow me to inspire you with a story about a great female scientist. Polish-born, French-educated Madame Curie. Co-discover of radioactivity. She was a hero of science until her hair fell out, her vomit and stool became filled with blood, and she was poisoned to death by her own discovery. With a little hard work, I see no reason why that can't also happen to any of you. Are we done? Can we go?
