An Irishman walks into a bar in Texas. He says, “I hear you Texans are a bunch of hard drinkers. I’ll give $500 dollars to anybody in here who can drink 10 beers back-to-back.”

The room is quiet. One man leaves. No one takes the Irishman up on his offer.

Thirty minutes later the man who left returns. He taps the Irishman on the shoulder. “Does your offer still stand?” he asks.

The Irishman says yes and asks the bartender to line up 10 beers on the bar. Immediately the Texan begins. He doesn’t stop until he has drunk all ten beers back-to-back.

The others in the bar cheer as the Irishman sits in amazement. He gives the Texan the $500 and says, “If you don’t mind me asking, where did you go for that half hour?”

The Texan replies, “Oh… before I took your bet, I wanted to go to another bar down the street to be sure I could do it.”
