The wonders of chemistry

Hummm... this just came to my mind, for no particular reason, mind you...

When somebody farts and stinks, and people around are disgusted, they
are just disgusted at the bad smell.

Now, I don't think most people come to think as deeply as this, but
what are smells? Smells are produced by chemical compounds that can
be detected by our noses.

But where did those "chemical compounds" come from? Certainly they
did not materialize out of thin air. Those came from the farting
guy's guts and through his butthole! Oh, and quite possibly before
those compounds were released into the air, they were in contact with
some fecal matter in the making.

Now that is gross!!!
