Why Simon told him no: Simon didn't quite see gold looking at Taylor's white locks: ''It is not just about the voice. And you prove that... This is a guy who should be singing backgrounds, not in the spotlight... [pointing to Paula and Randy] They will not put you in the final group to be judged by the public.''

Why Simon told him no: The Tony-nominated Rock of Ages Broadway star's now famous screeching was not the Brit's cup of tea: ''I just felt as I was listening to this that I just didn't want to be your next-door neighbor... I thought it was all over the place.''

Season and placement: Season 3, runner-up
Why Simon said no: The judge might not have literally said no, but his opinion of DeGarmo was clear: ''I know what the problem is... it's the horrible routine, the cutesy routine you do with your songs... the smiling is quite irritating.''

Season and placement: Season 5, fourth place
Why Simon told him no: ''I thought you rushed the song. I'm not sure I'm seeing a hell of a lot of charisma here. I'm not sure that I'm looking at a stand-alone star.'' Well, since Daughtry went on from Idol to headline a band, Daughtry, rather than a solo act, Cowell was onto something...

Season and placement: Season 5, 11th place
Why Simon said no: The judge didn't anticipate the number of ''Chicken Little'' fans in America: ''I think anyone over the age of 80 would love you... I don't think anyone under the age of 20 would be able to relate to you.''

Season and placement: Season 9, third place
Why Simon said no: ''This is a bad audition... No charisma, no effort, no attempt.'' Casey did put in a bit more effort following Simon's words — he took his shirt off for the ladies (Kara and Victoria Beckham) on the panel.

Why Simon said no: For once, it was about the voice: ''You can't start your songs well.''

Season and placement: Season 7, ninth place
Why Simon said no: ''I think you're a good singer. I don't think you're a contemporary singer. I think you're more like a hotel singer.'' At least it's better than Simon's patented cruise ship insult?

Why Simon said no: Actually, Simon, and the rest of the judges' panel, agreed to let Allen through to Hollywood. But only by a hair — Simon & Co. weren't too keen on him during his audition:
Simon: ''I think part of the problem, Kris, is you, because you don't have a huge amount of personality and your modesty is actually putting me off a little bit.'' Randy: ''I don't feel the star from it.'' Kara: ''I do think you need to work on, you know, when you walk on that stage, feeling like a star.''
