[He ponders for a second, trying to remember the experiment]

I'm probably remembering this wrong, but basically there's this experiment where a cat sealed in a box is exposed to a poison of some sort. I think it was radioactive or something? Anyway, there is no way to observe the cat while it's in the box, and the poison may or may no activate. If it does the cat will die. If it doesn't the cat will live. Until the box is opened there's no way to know if it activated.

So basically until observed the cat is both equally alive and dead. Kinda like if a tree falls in the woods and no one hears it does it make a sound. I think. I'm probably mis-remembering it though.
