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 home in County Cork, 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. “Me New Year’s resolution was to quit drinking!”
