Simon Cowell was in a particularly nasty mood on Wednesday night's American Idol, which featured performances by the Top 12 guys.
Cowell -- who has said he wants a girl to win this season -- ripped into Tim Urban, who replaced Chris Golightly after he was disqualified for not disclosing a prior record contract.

After the 20-year-old singer botched OneRepublic's "Apologize," Cowell sniped, "We absolutely made the right decision the first time around by not putting you through based on that performance."
Andrew Garcia, 24, wasn't spared from Cowell's acid tongue either. After performing Fall Out Boy's "Sugar We're Doing Down," the judge scowled, "It was too serious, too indulgent and not original enough."

Cowell slammed 19-year-old high school student Alex Lambert's singing of James Morrison's "Wonderful World" as the "most uncomfortable performance of the night."
"If it's uncomfortable for you, it's uncomfortable for people watching," he added.
Even Ellen DeGeneres got in on the mocking by playfully teasing the contestant for his mullet.
