Groupon knows social, as you can see with its latest Facebook post of a Banana Bunker—a container for a single banana, which you can absolutely purchase on the Groupon site.

Fans are going wild with the clever commentary. And Groupon is responding to every single comment, as innocently as a brand can while discussing what could easily be mistaken for a sex toy. Instead of a Banana Bunker. Because it's definitely a Banana Bunker.

If you were hoping to buy one, it's currently sold out. But keep hope alive, reader.

UPDATE: Groupon tells us how its social team not-so-innocently planned the post, which has become far and away the company's most popular ever.
