I think a strict antonym of "Crying Wolf" is someone who is right but not believed, rather than believed but not right, but your question wants someone who is believed.

Yes, the title of the question and the body don't really agree.

Are those words from Gene Wolfe really made up? In "Words Weird and Wonderful" (from "Castle of the Otter" and also in "Castle of Days") he says of "Shadow Of the Torturer" "all the words are real". In an appendix to SotT he says "I might have easily saved myself ... labor by [using] invented terms; in no case have I done so"

@anongoodnurse TIL. But as the article says, such a simple rule should be observed, even if it's wrong :-)

Shouldn't that be "hanged for stealing..."?

By the way, that should be 'happiness', not 'happy'. Or 'a happy, successful and safe 2020'.

"catching a whiff" is often used to mean getting a small piece of information which makes you suspect something.

I don't believe that 'chips' refers to gambling tokens, but to having finished your meal, i.e. you're done.

I'd say 1 makes a better slogan -- 2 is more passive.
