Happy St. Patty's Day

Three Irishmen, Paddy, Sean and Seamus, are stumbling home from the pub late one night and find themselves on the road that leads past the old graveyard.
"Come have a look over here," says Paddy, "It's Michael O'Grady's grave, God bless his soul. He lived to the ripe old age of 87."
"That's nothing," says Sean, "here's one named Patrick O'Toole... it says here that he was 95 when he died."
Just then, Seamus yells out, "Good God, here's a fella that got to be 145!"
"My God, what was his name?" asks Paddy.
Seamus lights a match to look at the marker more closely,"Miles, from Dublin," he says.
