Nearly four decades on, KFC has become a Chrimbo smash. Lines form outside many branches on Christmas Eve (which is the big event, as Christmas Day itself isn't a holiday in this mostly non-Christian country). Some families book more than a month in advance to ensure they'll get to enjoy their special meal together there.
We're pretty sure the bucket's cachet doesn't hold strong in these parts, but you could always give it a try. For that special Christmas shindig you've been invited to, forget Dom Pérignon and simply pitch up with a bucket of fried chicken. Just tell the host it's "Big in Japan."
And if they need proof, show 'em this YouTube clip. (There's more Christmas-related bonkersness on the KFC website.)
