Grandpa's Birthday

Today would be grandpa's birthday if he was still alive. He was a great Ford garage mechanic for over 35 years. One day he was out in the yard and he told his neighbor it was funny but he was seeing double. The neighbor said, now that's funny. I know a guy who was seeing double and he died. Grandpa went on into the house, sat down in his favorite chair and died, just like that. Isn't that something?
