quantum weirdness

good morning, herr doktor.
ah! my boy! look at this. I've proven that reality is completely dependent upon the minds of the subjects that perceive it!
what does that mean?
it means that, until you walked into the lab just now, you did not exist! just as a tree that falls in the forest makes no sound if no one is there to hear it.
but that's crazy. I'm here, aren't I? of course I existed before I came in.
not to me, you didn't.
and when I leave here?
to be is to be perceived! so you won't exist anymore! and neither will your bank account, for that matter! I wish I thought of this sooner. it's definitely going to be a money-maker.
