Tree

[Curtis]

if a tree falls off in the forest and nobody is there to hear it, does it still make a noise?

that one is difficult

[Kez]

Yes it does, you just don't hear it.

[Tash8]

no it doesn't because trees don't fall

[Curtis]

very good

[Curtis]

my guess is: others tree laugh at him and the laugh covers up the sound of the fall, so the people hear the laughter coming from the forest and a guy writes a book about it and how its haunted.

[Flamez]

[Curtis]

what if it lands in uncle phil?

The question says "if a tree falls". So you know that a tree has fallen, even if you're not there. We also know that if trees come down they indeed make a noise, so we can deduce that they do make a noise even if we don't hear it.

I've a better one:

We chop a tree down, then we chop it up?

Words of wisdom i heard from the great mans mouth, it is a weird one though.
