An elderly man in his eighties slowly stood up from his chair one afternoon and began putting on his coat. His wife, noticing his sudden burst of energy, asked, “Where are you going?”
He replied, “I’m going to the doctor.”
Concerned, she asked, “Why? Are you feeling sick?”

“No,” he said. “I’m going to get some of those new Via4ra pills.”
Without saying another word, his wife got up from her rocker and started putting on her sweater. Surprised, he asked, “And where are you going?”

She answered calmly, “I’m going to the doctor too.”
Confused, he said, “Why do you need to go?”

She looked him straight in the eyes and said, “Well, if you’re planning on using that rusty old thing again, I’m getting a tetanus shot.”
