I shot it repeatedly, even went so far as to pump the gun three times more
than the recommended number and shoot it at point blank range. Nothing.
I
put it in the dumpster and threw bricks at it. Nothing. Those CRTs are
actually pretty hard to smash.

Ah, the stupidity of youth. Being immortal was fun.

You need to surprise them from behind. Take off the case (and try not to
kill yourself) and shoot the back of it where it's a lot weaker. Way fun if
you float it (just the CRT) out in a pond, too.
