Not all "American Idol" winners are created equal. They can't all be Kelly Clarkson.

Jog your memory with the 9 "AI" champs whose careers hit a bum note.

9. Scott McCreery -- Season 10

Rings a faint bell.

8. Ruben Studdard -- Season 2

Oh yeah -- that guy.

7. Kris Allen -- Season 8

He sings that one song, right?

6. David Cook -- Season 7

A lot of dudes won this thing, huh?

5. Taylor Hicks -- Season 5

Uh ... whose dad is this?

4. Lee DeWyze -- Season 9

Nope, no memory.

3. Candice Glover -- Season 12

Who's that now?

2. Caleb Johnson -- Season 13

Come again?

1. Brian Dunkleman -- Season 1 Co-Host

Ah, the ultimate "Idol" flop.
