Well, Chapman owns a bookery, but It's too bad he never learned anything in school. The "I before E rule" was invented only for words that use ie or ei FOR THE LONG E SOUND. For example thief vs receipt.
Foreign, neighbor, eight, counterfeit, beige, sleighs, feisty, caffeinated, weightlifters, do not have a long E sound. Keith is not a word, it's a first name. Weird is actually the only exception, but English always has a few exceptions to its rules of pronunciation.
It's a picture of a sidewalk sign in the joke thread.
I don't think it was meant to be a definitive treatise on structure of the English language.
