X Marx the Spot

It was a typical evening at the Riveras. I sat down at the kitchen table getting ready to grade the kids' homework. I came across Christopher's homework. Oh cool! He's learning about the discovery of the polio vaccine. In 1953 Dr. Jonas Salk was said to have found a cure for polio. Then in 1960 Dr. Albert Sabin perfected and made it stronger. What a great piece of history here! Then there were multiple choice questions and answers. This should be easy. Question #3: Who invented the first cure for polio? A. Sabin B. the Marx Brothers C. Salk Christopher's answer: B - the Marx Brothers. And you thought the Marx Brothers were only good for laughs. GASP!
