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 slowly looked at him and said, "Well, last week I sat
Out here with no shirt on, and I got a stiff neck. This is your
Grandma's idea."
