These Battle Rounds on 'The Voice' (Tue., 10PM ET on NBC) have certainly created some memorable duets. But sometimes the union of voices creates a performance that's so bizarre it's virtually indescribable.

It was definitely the case with Serabee and Dia Frampton this week. They were paired up by Blake Shelton, and while it could have possibly worked, Serabee seemed to do all she could to make 'You Can't Hurry Love' unrecognizable. If Frampton hadn't been singing the actual melody, it would have been completely ridiculous.

It was as if Serabee thought that by singing runs and by treating Dia as a back-up singer so she could perform vocal acrobatics, she was going to impress the judges. Instead, she left them scratching their heads.
