Hexakosioihexekontahexaphobia: Fear of the number 666, because of its connection to the Beast in Revelation 13:18.

I avoid the number 666 about two-thirds of the time (that’s a mathematical pun).

I file this tidbit under the “Strange World” category, not because some people fear the number 666. That’s silly, but not necessarily strange. What’s strange is that somebody strung together a name for this fear. I feel a case of hippopotomonstrosesquippedalio coming on.
