A pastor was impressed by an older couple in his church who still seemed very enamored with one another.
Every time he saw them they were holding hands.
One day, he approached them after service and remarked, "You two are an inspiration. Acting like teenagers in love! You even hold hands all the time."
The wife, with an exasperated look, retorted, "That's not love reverend. It's the only way I can keep him from cracking his knuckles."
