Vaseline survey

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.'

And you thought it was gonna be a dirty joke...!

Shame on you.
