An adult grandson visiting his grandparents found his grandfather sitting on the back porch naked from the waist down.
"What are you doing, Grandpa?", the grandson asked.
The grandfather replied, "Last week I sat out here without a shirt on and I got a stiff neck. This was your grandmother's idea."
