You know what's sad? These aren't the initial auditions... these people have been screened prior to going through to Simon, Paula, and Randy.
So the screening judges send them through just so they can go on TV and make fools of themselves...
I really do feel bad sometimes when these people really think they're great and they get their dreams crushed... or the people who come on with crazy gimmicks. I mean, why?? Do you guys remember last year (I think it was) there was that girl who sang in the voice of the lion from Wizard of Oz? Seriously... why?
