I thought it was funny so I posted this here for you guys.
Life's great questions, answered?

BUT... the first one is wrong. it wouldnt make a sound.
sound is just waves untill it hits an ear, which then translates the waves INTO an audibility. thus if a tree falls in the forrest and nothings around to hear it, it makes sound waves, not sound.
and number two, neither cam first. if u look into the whole "Adam and Eve" thing, God made man first. Sooo, the ROOSTER came before the chicken, which came before the egg

I disagree ihitdrums, I think a sound is a sound regardless of whether it is heard, i don't think being processed changes its nature. You wouldn't say something wasn't red white and blue just because it wasn't being picked up by an eye... or would you, you commie bastard!
Anyway, if it's in a forets then there are many, many things that will hear it, trees for example, and all matter reacts to waves which is what sound is so it will be deteted so long as there is matter around it, which there must be.
And about the egg and chicken thing, it is actually all about creationism vs evolution.

The molecules moving through the air (caused by the energy of the tree
falling) are sound waves, ie. sound. Whether or not there is a transducer
(the human ear) to interpulate the sound waves or not is not relevant.
Now it's nap time for me.

I wonder if George Dunn provided any rationale for his answers - it would be interesting to find out how he thinks...

Dinosaurs had eggs and predate chickens.
I think that one's a pretty open and shut case.
.....that's genuinely funny, I'll be stealing that :)

Actually, the first one is likely correct. The original question was "If a tree falls in the forest when no one is there to hear it, does it make any sound?" Perhaps if the question pertained to "anything" rather than "no one" the above piece of overanalysis would be correct. However, the forest is teeming with life ranging from animal to insect. Animals tend to have more sensitive hearing than do humans and can hear sounds from farther afield. It is highly unlikely an entire tree could crash in the forest without reaching the ears of any living thing. Therefore, the first answer is more likely to be correct than not.
However, we could get into the size of the tree falling and then look at what is actually sitting on the forest floor. For example, perhaps it is actually a sapling we are doing the honor of calling a tree simply because we are unaware of when the two are differentiated. Then we find that a helicopter carrying a load of cotton dropped its payload by accident. Now we have a sapling falling very little distance onto a bed of cotton. The sound may be so faint that not even the animals present could perceive it.
Perhaps, though, the animals found the bed of cotton and went to sleep. If these were herd animals, the animal chosen as sentry would have a good chance of hearing it while those sleeping would not. If it were a solitary animal sleeping on the bed of cotton after a hefty meal, certainly this creature would not hear the sapling falling onto such a soft surface. If it were hungry, however, it might have hightened reactions to even the slightest sounds jarring it awake at the mere scratch of a leaf upon the cotton bed.
But would he have truly heard it? Is it hearing if one cannot discern what made the sound to begin with and identify it? This brings us to the great wisdom passed down to us from Ghostbusters when Dr. Ray Stantz uttered the now famous words, "Listen! Do you smell something?"

When a 'chicken' is not born out of an egg, it's not a bird, so it's not a chicken. A chicken is always born out of an egg, that is one of the things that makes it a chicken. That means the egg was first.

scientists have come down firmly on the side of the egg coming first. also, the book of genesis apparently says (according to mitchell symons, the author of trivia books) that the chicken come first, so it must be the egg - unless you choose to be brainwashed by the book of lies.

Hmmm.. I wonder if it turns into Zen if we transpose some of the answers ..
If a tree falls in the forest when no one is there to hear it, does it make any sound?
" ," very faintly.
Which came first, the chicken or the egg?
Yes.
Is the glass half empty or half full?
It's not, it only looks that way.
Now as to the question : What do women want from men?
The answer enters the realm of pure Zen: Six.
Indianapolis Mensan George Dunn answered the great questions of life for us a few years ago. Here they are:
If a tree falls in the forest when no one is there to hear it, does it make any sound?
Of course it does.
Which came first, the chicken or the egg?
The egg.
How many angels can dance on the head of a pin?
Six.
Can God make a stone so big that he can't pick it up?
Yes.
What happens when an irresistible force meets an immovable object?
One moves to the left.
What is the sound of one hand clapping?
" ," very faintly.
What do women want from men?
More attention to that question.
What constitutes success?
More.
Is the glass half empty or half full?
Half full.
Why are lost things in the last place you look for them?
Because when you find them, you stop looking.
Why is the sky blue?
It's not, it only looks that way.
