Beetlejuice is the extremely twisted bio-exorcist for hire. How do you hire him? Say his name three times, of course.
Originally hired by the the Maitlands, Beetlejuice lives in the model of the town built by Adam Maitland. The Maitlands hired Beetlejuice to scare away the Deetzes that moved into their home.
Preacher: Do you take this woman do be your wedded wife? Beetlejuice: [Runs off to the side mumbling to himself] Oh man, I don't know, it's kind of a big decision isn't it... I always said if I ever did it, I was gonna do it once and that was it... Beetlejuice: [Runs back to the altar and stands next to Lydia] Yeah, yeah, sure, right.
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?
