Anyone hear the old myth that a CRT could implode if damaged?

Several years ago, one old friend of mine said that he testified some CRT imploding, and for one of it he swears that one flying glass crossed very near it's neck...
He mention it when I challenged him: I never seen one imploded this manner; the only ones that I seen are modern ones and only produced the ait leaking sound, like some people mentions here (the ones I breaked like the examples cited here, and some that breaked by some accident). I'm also argued that, if one thing IMPLODES, the object will collapses into itself. But he explained: if one piece of glass is violently sucked to it's innards, it will kicks, sometimes in opposite direction, aka. it will fly away. And some side perhaps simply can shatter away due to physical force modulus.
