An Irishman goes into a bar in America and orders three whiskeys. The barman asks: “Would it be better for if I put all three shots in one glass?”
The Irishman replies: “No! I have two other brothers back at home, so every time I come into a pub, I order a shot for them both.”
The following week, the Irishman orders just two whiskeys.
The barman asks: “Did something happen one of your brothers?” “Oh no,” replies the Irishman. “I just decided to quit drinking!”
