"Quack Quack"
As this reporter was walking through the Amazon Room I was drawn by a sand that sounded something like a duck. Of course, with the tight security at the Rio, I knew this was surely not a duck but just the trademark noise of Paul "X22" Magriel.
Magriel had put a bet out on the turn and had two callers. The river came and the board read 
Magriel announced, "rainbow" which meant one of each color and in this case, a bet of 1,600. His opponent in the big blind almost instantly announced raise and put out 6,400. Magriel was silenced and very confused, trying to peer into the hooded sweatshirt of his young opponent and continually shaking his head. He eventually folded and said, "I have no idea what just happened there." Magriel still has plenty of chips with 34,000 which means he'll be making plenty of noise all day.
