Adam: What are your qualifications? Beetlejuice: Ah. Well... I attended Juilliard... I'm a graduate of the Harvard business school. I travel quite extensively. I lived through the Black Plague and had a pretty good time during that. I've seen the Excorcist 167 times, and it keeps getting funnier every single time I see it. Not to mention the fact that you're talking to a dead guy! Now what do you think!? You think I'm qualified?
