My Dad had four wives and who knows how many kids. Around 1990 the doc upped his BP meds and his pecker decided to call it quits. There was a general feeling of relief among that side of the family at large that the old horndog was finally out of action at just past the ripe old age of sixty. Roughly three years later Viagra hit the market in a big way and he was back to calling his old girlfriends, spreading the good news.
Flash forward a little under a decade and a half. His third wife dies and inside of three months he marries a woman down the road from the old farm I lived on as a young boy. I run into them just after they decided to tie the knot. He's going off on this long formal introduction. She and I are both looking at him like he was nuts. I've known her nearly all my life. He looks puzzled and says, "You two know each other?" She replies, "He was three years behind me in school. We caught the bus together and rode twenty miles round trip each way. You can say we've met a time or two." That's the only time I ever saw the old goat blush. She was the perfect wife for him, she didn't put up with any of his nonsense.
He was dead a little under two years after marrying her. Viagra, and a much younger wife when you're pushing hard at 80 will get you every time.
