Never Too Old For A Tetanus Shot
This old man in his eighty's got up from his chair and was putting on his coat. His wife said, "Where are you going?" He said, "I'm going to the doctor." She said, "Why, are you sick?" "No" he said, "I'm going to get me some of those new Viagra pills." So his wife got up out of her rocker and started putting on her coat and he said, "Where are you going?" She said, "I'm going to the doctor too." He said, "Why?" She said, "If your going to start using that rusty old thing again, I'm going to get a tetanus shot."
