"I don't think that there's a greater high... I challenge any high--heroin, marijuana, booze or anything--that if you know your stuff and you go into an exam knowing that you know it, there's no better high. There's no better high than sitting down and then opening the booklet and reading your first question and saying to yourself, 'Who made up this question? This person didn't-- You know, I'm ready to go.' There's no greater high than walking out after the exam and saying, 'How did you answer?' Or being the second or third person out of there."
