An old man in his eighties got up and was putting on his coat, when his wife said "Where are you going ?"
The elderly man replied "To the doctor."
Surprised his wife asked "Why, are you sick?"
"No" he said, "I'm going to get me some of those new Viagra pills." With that his equally elderly wife got up out of her rocker and started putting on her sweater.
Surprised, he asked "Where are you going?"
"I"m going to the doctor too".
She matter of factly said "If you're going to start using that rusty old thing again, I'm going to get a tetanus shot".
