Socket A? They were the ones with the "insta-fry" issue.

Socket A CPUs had no heatspreader (so very little thermal mass), and no integrated thermal throttle/shutdown logic. Deadly combination. If the HSF was missing or improperly installed.
Modern CPUs should throttle or shut down before permanent damage occurs. Not that I would intentionally rely on that by powering up with no HSF, but it's an extra safety net.

This one?

It's fake. The IC on the package looks fine, but yet it is launched almost uniformly out of the ZIF socket with smoke billowing out from underneath. It was rigged with a little explosive, clearly.
Tom's hardware actually did this for real back in the day, it actually looks like this: https://www.youtube.com/watch?v=NxNUK3U73SI
As you can see, the IC starts smoking/discoloring. It doesn't explode or even mechanically damage the PCB under the socket.
EDIT: Oh, lord, you weren't kidding about the table either, it's clean through for heaven's sake. Yeah, that's explosives. Completely and ridiculously fake.
