A man doing market research for the Vaseline Co. knocked at the door and was greeted by a young woman with three small children
running around at her feet. "I'm doing some research for the Vaseline Company. Have you ever used our product? She said, "Yes, my husband and I use it all the time." "If you don't mind my asking," he said, "What do
you use it for?" Mostly we use it for sex," she said.
The researcher was a little taken aback. "Usually people don't tell me that they use it for sex. Instead, they tell us that they use it on a child's bicycle chain or to lubricate a gate hinge and many other things, but very rarely sex.
As a matter of fact, we know that most people do use it for sex. I admire you for your honesty. Since you've been so frank with me, can you tell me exactly HOW do you use it for sex?"
The woman said, "It's no secret and I don't mind telling you at all. My husband and I have found that if we put it on the doorknob, it keeps the kids out."
"Senior citizens, although slow and dangerous behind the wheel, can still serve a purpose."
