Six Weeks to Live

A guy goes to see his doctor, and the doctor says, "Well, I'm afraid you have six weeks to live." The guy says, "Oh damn, well what should I do doctor?"

Is that supposed to help?" and the doctor says, "No, but it'll get you used to being in the ground."

The Irishman at Auschwitz

Two Irishmen are sitting in a bar.  Mick's looking particularly sad and Patrick asks him what the matter is.
Mick says, "Well, I knew that my grandfather had died in the war, but I've just found out that he actually died in the Auschwitz concentration camp."
Patrick says, "That's terrible, did he go to the gas chamber?" and Mick replies, "No, he fell out of the machine gun tower."
