I think I am in trouble

My oldest son Brock has been wanting to work on the Knowledge a thon questions lately. Which scares me since I said I would pay .25 cents per question he gets right. He has 50 questions. I had put only .5 cents on his brother since he was more willing to learn and doing so well on them. I guess even if he gets all of them right it won't be that bad. It's only $12.50. At least I know of one question he won't get right. He can't name the 7 continents. He only knows Austrailla as the one with Kangaroos. He all together forgets Europe and Asia. He likes to think of Antartica as New Zeeland. At Least that will say .25 Cents. : }
