A man was walking down the street when he noticed his grandpa sitting on the porch, in the rocking chair, with nothing on from the waist down. "Grandpa, what are you doing? " he exclaimed. The old man looked off in the distance and did not answer him. "Grandpa,what are you doing sitting out here with nothing on below the waist? " he asked again. The old man slyly looked at him and said, "Well, last week I sat out herewith no shirt on, and I got a stiff neck. This was your Grandma's idea! "
