Prof. Jeremy Mansfield
Here's an oldie but a goodie. If a tree falls in the woods and nobody's there to see it or hear it, does it make a sound?
William 'Will' Smith
Yes, yes, it does. Well, no, no it doesn't. Well, how *big* is the tree? Or how far away is this tree from the subway? And how far away is the woods from the ghetto? If the tree falls on a gopher, does the sound that the gopher makes count? What if it fall on Uncle Phil and he hurt the tree?
