An Irishman walks into a bar and orders three beers.

The bartender doesn’t say anything and gives him his three beers, the man drinks all three and leaves.

This goes on for a couple weeks and eventually the bartender gets curious enough to ask.

He says, “Why do you always buy three beers at once?”

The man says to the bartender, “Back in Ireland, me and my brothers would always drink together, when we moved away from each other we made a deal, no matter where in the world we are, every time one of us drinks, we drink for the other two, that way we can always share a drink together.”

The bartender is satisfied with the answer and goes back to the bar.

A couple weeks later the man comes in and goes up to the bartender and only orders two beers.

The bartender, trying to be kind asks the guy, “Are you okay, did something happen to one of your brothers?”

The man shrugs and says “No, I just stopped drinking.”
