This is the correct answer. Once they are unstuck they can be washed and used again.

Sigh. This is why I suggest lubrication and ultrasonic.

That is what I was going to suggest. Dropping them would also unstick them…

Have you tried unplugging them, waiting 15 minutes, and then plugging them back in?

It seems you have reversed the polarity. There is no going back from that.

This actually, really happened to my grandfather. He and my grandmother was moving on old couch down their stairs, and it got stuck in the bend. They could not figure out how to get it unstuck.

His solution was an electric chainsaw.

It was, by his account (and lack of couch in stairwell) an enjoyable and valid solution…

Listen- Strange bloggers on the internet posing riddles is no basis for a system of government. Supreme executive power derives from a mandate from the masses, not from some farcical tableware ceremony!

This is the thing, it’s not the shape that’s the issue here, it’s the glaze; the glaze has a high coefficient of friction (I believe that’s the correct term), which causes the two surfaces to bind together, so the trick is to break the bond at the point where the cups are stuck.
I had this happen with two ceramic bowls; sadly, I can’t remember how I got them unstuck!

I just used PB Blaster to free up my (obscenely expensive because keyed alike to another one) padlock on my scooter; that stuff is pure-dee fuckin’ magic.
