Groucho Marx is on vacation until the fall so some of his best shows were aired over the summer. Three couples are brought on stage to be interviewed and quizzed by Groucho Marx. Each is given $20 to bet as much as they want on four questions from the category they choose. The money doubles each time they get a question correct and the one with the most money goes on to answer the jackpot question with a chance of winning anywhere between $1000 and $3000!
