We all fart. There's no shame to it. People do not realise this but when we eat, we also swallow air. Gas is also produced when our food gets digested. More air! Now, when you have that much air inside you, it has to come out somewhere. That's why we all fart.
Do you know that not all fart sounds are alike? Bad Gas has a collection of 16 fart sounds in wav format. Go listen to them all. There's one that sounds like a motorbike gathering speed just before the engine abruptly cuts out. And another that sounds like a duck having a disturbing nightmare.
"A good fart should be treated like fine wine."
Now what kinda fart is yours? Mine just now sounded like a propeller plane landing in a swamp.
