Grandpa

A grandson came to visit his grandparents & noticed his
grandfather sitting on the porch in the rocker, wearing
only a shirt, naked from the waist down.

"Grandpa, whatcha' doing? Your weenie's out in t
he wind for all to see!" he exclaimed.  Grandpa
looked off in the distance, not answering. 

"Grandpa, whatcha' doin' sitting out here with
nothing on below the waist?" he asked again.

Grandpa looked at him & said,
"Last week I sat out here with no shirt on & got a stiff neck.
 This is your grandma's idea..."
