My grandfather died if that last year, plus of a host of other things(basically his body shutting down). Now even though it aint a funny disease I did find humour in it.
Example: The last 6 months he would watch "Titanic" every fucking day, but it was a new movie for him everyday. Drove everybody in my family nuts. I am sure he thought he rode the Titanic at some point i his life at that time and was trying to relive old memories.
He reminded me alot of Grandpa Simpson in the end. You know he was around in 19Somethinglikethat when they had a home in the statue of liberty which was the greatest thing since sliced bread, sliced bread having been invented the year before.
