"O! Say Can You See"
Upon a loud roar of cheers after the anthem concluded, tournament director Jack Effel thanked everyone for standing during the national anthem and mentioned that the staff wasn't quite sure on whether or not they would ask people to stand. On their own, most people did so, to which Effel said, "Thank you very much for all standing. You are the reason poker players are so special and what makes the WSOP."
Mind you, the clock did not stop during the anthem, but with respect to everyone, the staff has added three minutes back onto the clock.
