This has to be one of the funniest moments on 'American Idol' this season. The ladies of Group Seven just couldn't find a way to work with member Liz Bills.

Leaving her out of the group breakfast and early rehearsal, Bills' group mates made it clear they couldn't rock with her. Aside from choosing Gotye's 'Somebody That I Used to Know' like just about every other group in this episode -- a poor choice -- they just couldn't get it together.

Dogging her on-camera behind her back and pulling the fake cordial move was wack. They were tight when they heard Bills made it through to the next round. Shira Gavrielov's facial expression was priceless -- upset is an understatement.

Gavrielov had to come back in front of the judges after being eliminated to receive an explanation for her dismissal. She found out it was her own bad singing. Liz Bills clearly gets the last laugh.
