This reminds me of a hand at home game where the host was "setup" after he left the room to attend to his kid/dog/wife (can't remember). His brother made it so he was HU with a straight flush vs quad aces. The look on his "poker face" (or lack thereof) when the fourth ace came on the turn was priceless. He never saw the straight flush coming...

Of course we gave him his money back; his face made up for any money any of us lost that night -- and I just met the guy.
