A market researcher called at a house and his knock was answered by a young woman with three small children running around her.©OFFICEJOKES.NET

He asked her if she minded replying to his questions and when she agreed, he asked her if she knew his company, Cheeseborough-Ponds.©OFFICEJOKES.NET

When she said no, he mentioned that among their many products was Vaseline and she certainly knew of that product. When asked if she used it, she answered, ''Yes, we use it when we have sexual intercourse.''©OFFICEJOKES.NET

The interviewer was amazed. He said, ''I always ask that question because everyone uses our product and they always say they use it for the child's bicycle chain, or the gate hinge or some other purpose. But I know that most people really use it for sexual intercourse, they just don't like to say so. Since you've been so frank, could you tell me exactly how you use it?''©OFFICEJOKES.NET

''We put it on the doorknob to keep the kids out.''
