In ITT, there's always an uncontrollable laughing fit that Claudia went through and put in the the 'best of' towards the end of the series.
Forumites will decry 'fix fix fix' when they favoruites are out (or when their biggest threats/rivals to their fav's still in).
There's always someone who's smug. Denise (s2), Zoe, Darren, Colin (s3), Emma, Ray (s3), Matt Di Angelo (s5), the top four in series six.
Bruce will always crack some jokes and then desperately try to make the audience to laugh and pretends to be stroppy when one can still hear the pin drop in the studio.
Someone's always fake in the show: Zoe in series 3, Emma in series 4, Kelly in series 5, and, Christine and Lisa in series 6, and oftentimes the fake ones are women.
Oh, forumites bitching over some (usually women) celebs being boring, teachers' pets, no techniques, and resent when others challenged them, saying they are NOT jealous or whatever, and then went on bitching about their body parts, hair, make-up and dresses and the like...
