Tom "Durrrr" Dwan has been wearing funny hats for the first two days of this tournament because he lost a prop bet against Alan "TheUsher" Sass. They bet whether or not Dwan would show up on time for Day 1, and Dwan was late.
It appears that the bet has expired, perhaps along with Sass's elimination yesterday, because Dwan is sitting in the field dressed normally. No more hat.
Dwan started the day with 98,800 in chips, and currently has roughly 183,000.
