My career as a personal-lubricant pitchman started with a favorited tweet on Stellar that linked to Amazon where, for just $1,495, anyone could purchase a 55-gallon drum of Passion Natural water-based lubricant (and save 46 percent off list!).

“What are you going to do with all this lube?! Wrestling match? Biggest adult party ever?” the pitch for the 522-pound tub went. “If you are looking for a simply jaw-dropping amount of lube, Passion Natural Water-Based Lubricant is ready to get the fun started with this 55 gallon drum! With its superb formula you will have a natural feel that keeps you moist longer and also works great with all toy materials. Easily washes away with warm water and mild soap. You may never run out of lube again!”

While it isn’t eligible for free Amazon Prime shipping, freight is a reasonable $20.95. There were entertaining customer reviews, often the best part of the odd products for sale on Amazon, and, since it was Valentine’s Day, it was timely.

Amused, I posted it to Facebook with the line “A 55-gallon drum of lube on Amazon. For Valentine’s Day. And every day. For the rest of your life.” And then I went on with my life.

A week later, a friend posts a screen capture and tells me that my post has been showing up next to his news feed as a sponsored story, meaning Amazon is paying Facebook to highlight my link to a giant tub of personal lubricant.

Other people start reporting that they’re seeing it, too. A fellow roller derby referee. A former employee of a magazine I still write for. My co-worker’s wife. They’re not seeing just once, but regularly. Said one friend: “It has shown up as one on mine every single time I log in.”

I’m partially amused that Amazon is paying for this, but I’m also sorta annoyed. Of course Facebook is happily selling me out to advertisers. That’s its business. That’s what you sign up for when make an account.

But in the context of a sponsored story, some of the context in which it was a joke is lost, and I’ve started to wonder how many people now see me as the pitchman for a 55-gallon drum of lube.
