An Irishman walks into a bar in Chicago and says to the barkeeper, "I'll have a wee dram of Irish Whiskey. And another just like it." Every time he re-orders, he asks for the same thing.
This goes on every day for several weeks and finally the barkeeper asks, "What's up with you always ordering two whiskeys at the same time. Why don't you just get a double?"
The Irishman says, "Oh, me brother is back on the old sod, and when I came to America, we agreed that every day after work, we'd have a drink to toast each other's health."
The bartender responded that that was a nice thought and every day, the Irishman came in and asked for two drinks at a time.
One day, the Irishman just orders one whiskey. The bartender was concerned and asked, "Is everything OK with your brother?"
"Oh sure," the Irishman answered, "but I saw my doctor yesterday and he told me I needed to stop drinking."
