Paula Abdul vs. Jason Castro
During her eight-season run on Idol, Paula Abdul had her fair share of slip-ups and odd moments. Things got seriously weird, even by Paula standards, in one Season Seven episode. Upon being asked to judge contestant Jason Castro's performance, Abdul appeared visibly flustered before proceeding to tell the contestant she disliked his second performance. Problem was, he'd only performed once. "This is hard!" she protested to laughter. Oh, Paula.
