An Irishman goes into a bar, and orders 3 Guinesses. He takes them to a table, and proceeds to drink them. The bartender walks up to him, and says, "You know, you could order them one at a time, I don't mind serving you". The Irishman says "No, you don't understand. I left my brothers Shaunessy and Liam back on the Green Isle, but we all promised that we'd all drink together every evening at exactly 4 o'clock". The bartender nodded appreciatively.
This went on for several months.
One day, the Irishman came in and ordered 2 Guinnesses.
The bartender solemnly handed them over. After a bit, he approached the table and said "I'm so sorry for your loss!"
The Irishman said "What loss? I just quit drinking!"
