Je le vois, mais je ne le crois pas.
"I see it, but I don't believe it." Famously used by Cantor (in a letter to Dedekind) to express his suprise at the discovery of the cardinality of lines, planes, and spaces: they're all the same.
Monte Cook, on his New Year's Resolutions:
"Do not release any product with the word 'fane' or 'eldritch'. At least in the title. Well, maybe just one."
Monte's love for particular words, especially the two above, has not gone unnoticed --- and his "fane fane fane fane" post has, hopefully, not passed out of collective memory yet.
"We elves are a happy and peaceful family (blatantly ignoring drow). We prefer to remain so, but your intrusive meddlings have crossed the line; you found out about how we butchered and slaughtered each other way back in the day. For that, your lives are forfeit. I pray that your next incarnations are less curious." -cignus_pfaccari
