First, I'm new to this forum. There are so many good Bourbons and so little time.
I don't think there's a Bourbon fan alive who hasn't seen The Hustler at least 5 times (J.T.S. Brown, no ice, no glass). And I'm a huge fan of the movie. But I have my own theory why Fats, when ordering White Tavern Whiskey during the first big match, said to Preacher, "Get it at Johnny's." That was his way of signaling to Preacher to alert Bert Gordon that a big game was going on and to get in the action. Others have commented that Fats was drinking a non-alcoholic beverage during the game, which explains why he won and why he didn't look tired after 40 hours of play. But if that were the case, then why later did Bert Gordon tell Eddy, "He drank just as much whiskey as you." This, after Eddy used his drinking as an excuse for losing that match.
Maybe the world will never know the answer. Maybe it's better we don't. I have just one last thing to say, "Just tell me where I can find him, friend."
