I'm going to go sideways about this thread. Here's a few Holy Crap moments that didn't include people singing either wonderfully OR horribly:

. Kelli Pickler- Bohemian Rhapsody- I was stunned when she sang this, and absolutely shocked at her appearance. An amazing moment. She hadn't actually done a great job of singing, but she HAD pulled it off. "My god, she's going to win this," I said to my wife, who agreed (we were wrong).

. Kristy Lee Cook- Proud To Be An American- Facing sure elimination after 3 close calls, what recently used successful strategies could Kristy do to save herself? Sing better, like Phil? Sing worse, like Sanjaya? Or disrobe, like Haley? She chose to do none of the above, but tried shamelessly pandering to her audience instead. And much to my disgust, it worked. Bleh.

. 4 wild card contestants being told they would NOT be allowed to sing, season 3 semifinals. Still AI's lowest, slimiest moment EVER.

. Jordin being made to think she was voted off, season 6 Idol Gives Back special. More sadistic bullshit.
