A guy pulled into his grandpa’s driveway and noticed the old man was sitting out on the porch, in his rocking chair, with nothing on from the waist down.
“Grandpa,” he said, “What are you doing?”
His grandpa, embarrassed, looked off in the distance and did not answer.
The guy repeated himself, “Grandpa, what are you doing sitting out here with nothing on below the waist?”
Finally the old man looked over and said, “Well, last week I sat out here, without a shirt on, and I got a stiff neck.”
He cleared his throat, then continued, “So this…” he motioned to his junk, “Was your Grandma’s idea!”
