This old man in his eighty's got up and was putting on his coat. His wife asked "Where are you going?" He said "I'm going to the doctor." And she asked "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 sweater and he asked "Where are you going?" She said "I'm going to the doctor too." He asked "Why?" She said "If you're going to start using that rusty old thing again, I'm going to get a tetanus shot."
