Mick's Grandfather

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.
