You never know what you'll learn when you ask questions for a living:

 

A market research company was conducting interviews for a large consumer products company.  One of the interviewers contacted a women in rural Canada who had several small children running around her, getting under her feet.

 

He asked if whe had heard of the company, and the women's reply was "no".  He mentioned that among their many products was Vaseline.  When asked if she was familar with the product the woman replied, "yes".

 

He asked what she used Vaseline for, and the woman replied; "To assist in Sexual intercourse".

 

The interviewer was amazed.  "When I ask people what they use Vaseline for they usually say that it's to grease a bicylce chain, or the gate hinge; but  I know that most actually use it during sexual intercourse.  Since you been so frank, could you tell me exactly how you use it?"

 

"Yes, we put it on the dorrknob to keep the children out."
