Door to door Vaseline survey

(this might have made more sense back in the days when people actually went door-to-door instead of having everything on the net)

A man knocks on the door of a house, and a lady in her late 20's answers.

"Good afternoon, ma'am, I'm a representative of the Vaseline Petrolium Jelly company, and we're doing a survey about our product. Do you have a couple of moments?"

She says "Why yes, sure. Go ahead"

"First, do you use our product in your home?"

"Yes, certainly."

"May I ask what you might use the product for?"

"Oh, probably all the expected things. I put it on small scrapes the kids get on the playground. Chapped lips in the Winter. My husband applies a thin layer on his tools to prevent rust form forming. Nothing unusual."

The man writes all this down, and continues.

"Ma'am, I apologize for asking this next question, but it's on the form; your answers will be kept strictly confidential, and it helps us make a better product. Do you and your husband use Vaseline for any sexual purposes?"

She pauses, blushes slightly, and glances around to see if any neighbors are within earshot.

In an embarassed voice and a slight giggle, she says "Well... yes, we do".

"Again, maam, I apologize, but can you please be specific about exactly how you use the product?"

"Well..." she says "... we put it on the doorknob to the bedroom so the kids can't get in."
