Casey Abrams and Haley Reinhart's duet destroys Lauren Alaina, Scotty McCreery on 'American Idol'

Lauren Alaina and Scotty McCreery kick off "American Idol" with a suprisingly flat country music duet. 

It's followed by a zombie version of the traditional car commercial, and then Casey Abrams and Haley Reinhart jazzing it up together; she's really good, actually, totally steals the show -- sounds like a pro. He's pretty good as well. Where was this last night, guys?

Big cheers from the audience and a standing ovation from the judges. They give them big praise; irony, of course, is one or both of them could be on the chopping block.
