Ong's Hat was one of the earliest internet-based secret history conspiracy theories created as a piece of collaborative fiction (aka Incunabula) by four core individuals, although the membership propagating the tale changed over time.
Famous quotes containing the word hat:
“Few colors last; with their eternal thirst, time and light suck on them, and they bleach the black doctor’s hat until it’s grey like a dunce’s cap.”
—Franz Grillparzer (1791–1872)
