177 is OK
It was meant as a joke, but the word “OK” has become iconic. It first appeared in print in the Boston Morning Post. From AtlasObscura:
As Allan Metcalf details in OK: The Improbable Story of America’s Greatest Word, okay made its first printed appearance in the March 23, 1839 issue of the Boston Morning Post, as part of a playful diatribe directed at a rival paper, the Providence Journal.
