The wife admits to using it for Sex

A man doing market research for Vaseline knocked on a door and was greeted by a young woman with three small children running wild around her feet.

He says, "Good afternoon, Ma'am. I’m conducting a survey for Vaseline. Have you ever used our product?"

She nods enthusiastically, "Yes, my husband and I use it all the time."

Intrigued, the researcher asks, "If you don't mind me asking, what do you use it for?"

Without hesitation, she replies, "We use it for sex."

The researcher is taken aback and says, "Wow! Most people lie and tell me they use it on their kid’s bike chains or to fix a squeaky hinge. I really admire your honesty."

Feeling brave, he asks, "Since you’ve been so open, can you tell me exactly how you use it for sex?"

She smiles and says,

"Sure! We smear it all over the doorknob to keep the kids out!"
