From Encyclopedia Dramatica
Austin Fullmer is a 19 year old second-generation Scientologist who completely failed at his American Idol audition, and freaked out Simon Cowell. Austin's real job is processing sewage so that it can be re-used in LA as drinking water. Appearing at one of the early auditions, when people are most likely to be complete retards and utterly lacking in talent, Austin attempted to sing a song by lame 1970s rock band Cheap Trick.
How do we know he's a Scilon?
Apart from his horrible fashion sense, which is common in Scilons, former OSA agent Gary Scarff ("Smurf" on Why We Protest) declared that he has known Austin's parents for years, and that they are hardcore. His batshit screaming at the judges has also been identified as an attempt at Scientology magic (Tone 40) to make people do what he says. Scientology works and it helps people.
Austin Fullmer is part of a series on YouTube.
