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."
