The old feller replied, "Yep. It comes from clean living. Why, I know I live a good, clean, spiritual life."

The doctor asked, "What makes you say that?"

The old man replied, "If I didn't live a good, clean life, the Lord wouldn't turn on the bathroom light for me every time I get up in the middle of the night."

The doctor was concerned. "You mean when you get up in the night to go to the bathroom, the Lord Himself turns the light on for you?"

"Yep," the old man said, "whenever I get up to go to the bathroom, the Lord turns the light on for me."

The doctor let it go, but when the old man's wife came in for her check up a couple days later, he felt he had to let her know he was worried about her husband

"I just want you to know," the doctor said. "Your husband is in fine physical shape, but I'm concerned about his mental condition. He told me that every night when he gets up to go to the bathroom, the Lord turns the light on for him."

"He what?" she cried.

"He said every night when he gets up to go to the bathroom, the Lord turns the light on for him," the doctor repeated.

"Aha!!!" she exclaimed. "So he's the one who's been peeing in the refrigerator!"
