A man walks into a bar and taps an Irishman on the shoulder. He says: “I hear all you Irishmen are hard drinkers. Well, I’ll bet you $10 that you can’t do this.”
The man orders 10 beers, then gulps them all down, one after the other. When he’s finished, he turns to the Irishman and says: “Try that.”
Instead, the Irishman gets up and runs out of the bar. The man laughs and considers himself the winner.
Fifteen minutes later, the Irishman walks back into the bar, taps the man on the shoulder, and asks: “Hey, pal, that bet o’ yours still stand?”
The man shrugs and says, “Sure.” So the Irishman orders 10 beers and immediately slams them all down.
While the man forks over the money, he says: “You know, I thought you were running out on the bet. How come you left?”
The Irishman says: “Oh, I wasn’t sure I could do it, so I went to another pub to practice first.”
