> Someone makes an Entertainment so unbelievably good that anyone who watches it is immediately stupefied and has no will to do anything but watch the Entertainment over and over. This Entertainment becomes a potent terrorist weapon since it can essentially take out anyone to whom it's broadcast.

There's a Monty Python sketch where someone comes up with the funniest joke in the world and dies laughing after penning it. It's eventually learned that anyone who reads or hears the joke immediately laughs themselves to death. Of course, eventually the army gets a hold of it to use as a weapon.
