I must say I’ve been mostly enjoying this current advertising campaign to celebrate weirdness, but this easily takes the cake.
Reminder: it’s not 11 herbs and spices in there. Back in the 80s, this guy Poundstone bought a bag of the “11 herbs and spices” mix from a KFC employee and took it to a food chemistry lab for analysis: salt, pepper, and MSG.
Presumably the Colonel himself used the full eleven, but it is speculated that they were dropped after he sold the company.
