Phil Hellmuth called a MP raise while in the BB to see a flop. He then called a continuation bet before they both checked the turn. Hellmuth then led out on the river and his opponent folded. Hellmuth looked at his cards and threw them in the muck, jokingly berating his own play.
He then grabbed them out of the muck to show and then started talking to his opponent about how he could've extracted more chips out of him.
