On a somewhat related note, I actually had this happen recently on the stove. I've done it a few times over the years in the microwave, and I didn't even think it was really possible to have happen on the stove. Plain stainless steel pot, small, good condition but still a couple years old. You'd think plenty of nucleation sites, right? Filled it with 195F water from the insta-hot tap, and put it on my induction stove and turned it on high to push it up to a roiling boil. But after 30 seconds -- nothing. Not a single bubble in the pan, which is weird all by itself. And at this point the range is pumping a fairly ridiculous amount of energy into what is already hot water. So I thought "it can't really be superheating, right? on the stove??" and then grabbed the pot and swished it really good while stepping back. Sure enough, it instantly erupted into a furious boil. I'd guess I'm unlikely to ever run into that situation again. The stars had to align pretty well, I think.
