Clue/Question: The expensive walnuts didn’t taste right and weren’t what they were – – –
Answer: CRACKED UP TO BE
(I think this qualifies as more of an idiom than an adage, but either way I’m not sure of its origins. Does it have something to do with nuts, that need to be cracked? I’m seeing now that it’s old English/Irish for not being what it’s talked/rumored up to be. Okay? By the way, stale, funky nuts are very disappointing.
No new clue words today. Two of the jumbles are coming up as new, while we’ve definitely had “ceyda” and “hnakt” before. They all came to me very quickly today. I really don’t hear “proven” that much these days. It seems to me that they use proved much more frequently. By the way, proved is not in the ralis95 world famous clue word database, Hoyt! Just sayin’, as they say! The answer letter layout was a terrific thirteen letter jumble. But, the final answer came to me immediately.
Cute cartoon of an older couple, disappointed with their pricey purchase. Jeff went with two different kind of nut crackers, the ornate toy soldier looking one, that you traditionally see at Christmas, and the more conventional handheld version. Maybe these folks can get a refund! Be well and do good, friends.) — YUR

I can’t say about the others, unc, but when you started talking about “idiom” and “adage” you just went over my head.
Unc, I’m a simple Marine; I didn’t learn how to read until yesterday. 😦
Looks like you’re doing very well for a newbie, lwc! — YUR
