Paddy and Seamus were deep in the bottle one day when, in a contemplative mood, Seamus suggested they keep a bottle of the finest aged Scotch to have poured over their grave when they died. Both agreed, and purchased the finest bottles around.
Years later, Seamus was lying in his bed in the hospital, and the end was near. His family and closest friends had all gathered, and Seamus weakly motioned for Paddy to come closer. "Don't forget the bottle, and the promise we made in our youth," he whispered. "Aye," replied Paddy, "I do remember, and have the bottle that has sat untouched lo these many many years, to be poured out on your grave. But, my friend, you wouldn't mind if I filtered it through me kidneys first?"
