A guy tries to impress his date with his knowledge of wine. He tells the wine steward to bring a bottle of 1985 Sterling Cabernet Sauvignon from the Carneros district. After tasting it, the young man berates the steward. “This is a 1992 vintage from the Diamond Creek vineyard in the Mayacamas range. Please bring me what I ordered.”

Watching from the bar, an old drunk comes up to the table with a glass in his hand and says, “Can you tell me what this is?”

Winking at his date, the young man sips from the drunk’s glass.

“Christ, this tastes like piss!” he exclaims, spitting it out.

“Yeah,” says the drunk, “but what year?”
