Maybe it's just the hands they chose to show, but she did come off looking veeeeeery douchey.
It wasn't just calling the clock in that hand either - the one where someone asks how much she has and she just waves a finger in the direction of her stack... douchey. OK, you don't have to answer, you can get the dealer to count it for you. But don't make them do that and be an ass at the same time.
I'll give her the benefit of the doubt, she doesn't seem stupid and it's entirely possible that was an image she was creating deliberately to try and put people off their game. She definitely looked like a douche though.
As for putting her in the same category as Matusow, Kahn and Hellmuth, I dunno. No matter how big an ass Hellmuth makes of himself, he's always got the fact that he owns 11 bracelets to fall back on. That's not something Tiffany Michelle has.
And no matter how obnoxious Matusow or Kahn have been, they've had
some likeable qualities to offset them. Matusow blows up and calls people donkeys, but at the same time you can tell he's got a serious love for the game and he really, seriously wants to win and play his best. Hevad Kahn was much the same, I think - what he was doing seemed to be a lot of hyperacitve yet geniune enthusiasm for the game. Tiffany Michelle didn't really show that.
