A man noticed his grandfather sitting

on the porch, in his rocking chair, with nothing on from the waist down.

Grandpa, what are you doing?" he exclaimed.

The old man looked off in the distance with out answering. Grandpa, what

are you doing sitting out here with nothing on below your

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 got a stiff neck. This is your grandmother's

idea."
