A man doing market research knocked on a door and was greeted by a young
woman with three small children running around at her feet.
He says, 'I'm doing some research for Vaseline. Have you ever used the
product?'
She says, 'Yes. My husband and I use it all the time.'
'And if you don't mind me asking, what do you use it for?'
'We use it for sex.'
The researcher was a little taken back.. 'Usually people lie to me and say
that they use it on a child's bicycle chain or to help with a gate hinge.
But, in fact, I know that most people do use it for sex.
I admire you for your honesty. Since you've been frank so far, can you tell
me exactly how you use it for sex?
The woman says, 'I don't mind telling you at all. My husband and I put it
on the door knob and it keeps the kids out.[:x)]
