Are you?

We are watching Are You Smarter Than A 5th Grader right now. I've never watched it before so it's kind of fun. The guy's 2 questions away from 1 million dollars. It'll be interesting to see if I know the answers to the questions they ask. The last question was 'How many cups are in 5.5 gallons?' and we knew the answer, but I bet it's much harder to think of the answers, even if they are easy, under that much pressure.
