Advertising content on a social media page isn't always glamorous or creative but Groupon has managed to go down in history for making their Facebook ad content uproariously funny. The online retailer made a Facebook post declaring they are "contractually obligated" to let their audience know when the very phallic "Banana Bunker" is featured on their site. The "Bunker" is basically a sheath designed to protect bananas from wear and tear, but saucy commenters immediately made the NSFW connection and absolutely went for it on the post.
The engagement doesn't end with the commenters - whoever is in charge of Groupon's social media made sure that the responses were just as clever and just as raunchy. The ad did so well that the company brought the product back a few month's ago. We almost want to buy one ourselves..
