"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 EXORCIST ABOUT A HUNDRED AND SIXTY-SEVEN 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?" - BEETLEJUICE
