Best: Simon Cowell Gets Soaked, Season 3
Love him or loathe him, Simon Cowell helped put American Idol on the map with his scathing critiques of contestants, especially during the regional auditions. In Season 3, though, one Idol reject took the acid-tongued judge to task. Cowell couldn't stop laughing as 18-year-old Jonathan Rey bizarrely butchered Shakira's "The One," saying, "I think we're going to have to cancel this competition — that was terrible." The guy then calmly walked up to the judges' table as if to shake hands, but instead he picked up a cup of water and threw it at Cowell. Security quickly swooped in, but by that time, Simon had been soaked.
