An old man in his 80s got up and put on his coat.

 

“Where are you going?” his wife asked.

 

“I’m going to the doctor,” he replied.

 

“Why?” 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 began putting on her sweater.

 

“Where are you going?” the old man asked.

 

“I’m going to the doctor too,” she replied.

 

“Why?” he asked.

 

“If you’re going to start using that rusty old thing again, I’m going to get a tetanus shot!”
