KFC hid its secret recipe in its Twitter follow list and waited for someone to notice

In 2017 KFC's US brand was mid-turnaround under Wieden+Kennedy Portland, which had already revived Colonel Sanders. The team wanted to celebrate the world's most famous trade secret — the blend of 11 herbs and spices — without spending on media. Their answer cost zero production dollars: KFC's Twitter account unfollowed all 35,000 accounts it followed, then followed exactly 11 new ones — six men named Herb and all five Spice Girls.

Then they waited. For about a month nobody noticed. On October 19, 2017, Twitter user Mike Edge (@edgette22) cracked the joke and tweeted a screenshot. The tweet passed 480,000 likes and 200,000 retweets within a day, hit #1 on Reddit's front page, and landed KFC on the Today show — with Ford's chief brand officer publicly offering the anonymous author a job. KFC completed the loop by sending Edge an oil painting of himself getting a piggyback ride from the Colonel, earning a second wave of coverage.

Wieden+Kennedy reports the stunt drove nearly 2.5 billion impressions in two weeks, with D&AD recording 360,000 mentions — all from a change to an account setting. The work won a Silver Pencil in Social Media at The One Show 2018 and Graphite and Wood Pencils at D&AD 2018.

The follow list itself is free, unclaimed ad inventory

Zero media spend: the follow list was free, unused inventory every brand already owns.

A single decodable answer turned discovery into a prize, so the finder broadcast it himself.

The joke compressed KFC's core brand asset — the secret recipe of 11 herbs and spices — into one screenshot.

Patience created authenticity: because KFC never announced it, the reveal felt fan-owned, not planted.

The painting reward extended the story into a second news cycle without new creative.

Every owned surface, even a follow list, is potential media. A buried joke with a single correct answer converts discovery into participation — the finder becomes your media channel for free.

The stunt became a textbook example of earned-first social thinking and platform-native Easter eggs, cementing Wieden+Kennedy's KFC run as one of the most awarded brand comebacks of the decade. KFC kept the 11 follows in place for years, and the '11 Herbs & Spices' follow list remains a running reference whenever brands hunt for hidden inventory in their own channels.
