If you show up at the next American Idol open auditions with 10,000 other hopefuls thinking you're going to actually sing in front of Randy, Paula, and Simon -- think again. First of all, the celebrity judges don't even show up until callbacks are scheduled. And only a small percentage of "the best" and "the worst" contestants actually make it to callbacks. Oh yeah, if you want to make it on TV -- you'd better have a gimmick.
