Haha, who saw the last few episodes of Silicon Valley? The used
Schrodinger's cat to mess with a guy.

How do we know it even fell to be asking the question?
But most importantly, did the tree fall on anyone?

Tricky question. May not even make sense at the quantum level. But
theoretically, in the layman's terms, yes it would. If the sound is a
product of the collapsed realisation of the tree, then the sound would be
different. But that's not the weirdest part. If you don't see how the
tree falls but then listen to the sound it makes afterwards, the tree would
appear to *retroactively fall differently* in order to accommodate the
sound you hear. In other words, suppose the tree could fall either left
into the water, or right on to the ground, the reality is that it falls in
both directions till you hear the sound it makes. And if you position
yourself in a way that you can only hear the one sound, then it will only
fall on that side. So by changing the way you hear how the tree falls, you
change what happened in the past!

In other news, if a tree falls in the forest and nobody observes it,
does it make a sound?

The answer is that it's a trick question. The tree exists in a
superposition of falling down and not falling down until someone sees it.*
