Yep, I remember a TV segment about this decades ago. They showed kids in a remote African village proudly sporting “Super Bowl Champion Buffalo Bills” t-shirts, etc.
This is true.
A few years ago I worked in Angola in the oil and gas industry. I remember seeing a “Dale Earnhardt, NASCAR Winston Cup Champion” tee shirt for a year that he definitely did not win the Cup. This was 10 years or so after his death, so they are probably stored long enough for people to forget, too.
