Gramp's Hard Pecker!

An old man woke up in the middle of the night and found, to his utter astonishment, that his pecker was as hard as a rock for the first time in two years. He shook his wife by the shoulder until she woke up and showed her his enormous boner.

"Check this out!" he happily exclaimed. "What do you think we should do with it?"

With one eye open, his wife replied, "Well, now that you've got all the wrinkles out, now would be a good time to wash it."
