Just chck the definitoin of flatulence on wikipedia
http://en.wikipedia.org/wiki/Flatulence
"Flatus is expelled under pressure through the anus, usually accompanied by a distinct odor and sound, a process known informally as farting"
"A small amount of solid or liquid fecal matter in fine particulate aerosol form may also be expelled, and included, along with flatulence."
"The noises commonly associated with flatulence are caused by the vibration of the anus, not by the buttocks. The sound varies depending on the tightness of the sphincter muscle and velocity of the gas being propelled"
"The pitch of the flatulence outburst can also be affected by the anal embouchure"
CURIOSITIES:
Curiosities
* According to "The Great Fart Survey" [4], 39% of those who participated like the smell of their own farts.
* Le Petomane "the Fartiste" a famous French performer in the nineteenth century as well as many professional farters before him did flatulence impressions and held shows. Mel Brooks named his fictional governor (played by himself) William J. LePetomaine in the Western spoof film Blazing Saddles.
* Emperor Claudius passed a law legalizing farting at banquets out of concern for people's health.[14] There was a widespread misconception that a person could be poisoned by retaining flatus.
* Flavius Josephus reports in The Wars of the Jews that a Roman soldier raised his clothes and farted at the Feast of Unleavened Bread. This profane act so enraged the Jews that it caused a riot, during many thousands were killed.[15]
* According to Herodotus, when the Pharaoh Apries demanded his general, Amasis, appear before him, "Amasis, sitting on horseback, raised his leg and farted, telling the messenger to take that back to Apries."[16] Amasis later deposed Apries.
* An apocryphal story about Edward de Vere, Earl of Oxford is that he farted while swearing loyalty to Queen Elizabeth I and consequently went into self-imposed exile for seven years. After his return, the Queen was reported to have reassured de Vere: "My Lord, I had quite forgotten the fart." (John Aubrey, Brief Lives)
* In August 2005, New Scientist magazine reported that inventors Michael Zanakis and Philip Femano had been awarded a US patent (U.S. Patent 6,055,910 ) for a "toy gas-fired missile and launcher assembly". The abstract of the patent makes it clear that this is, in fact, a fart-powered rocket:
"A ... missile is composed of a soft head and a tail extending therefrom formed by a piston. The piston is telescoped into the barrel of a launcher having a closed end on which is mounted an electrically activated igniter, the air space between the end of the piston and the closed end of the barrel defining a combustion chamber. Joined to the barrel, and communicating with the chamber therein, is a gas intake tube having a normally closed inlet valve. To operate the assembly, the operator places the inlet tube with its valve open adjacent [to] his anal region, from which a colonic gas is discharged. The piston is then withdrawn to a degree producing a negative pressure to inhale the gas into the combustion chamber to intermix with the air therein to create a combustible mixture. The igniter is then activated to explode the mixture in the chamber and fire the missile into space."
* British inventors have also patented fart-related ideas, such as "A fart collecting device," which includes a drawing of the invention deployed and ready for action, with helpful numbers to identify the various components. "It comprises a gas-tight collecting tube 10 for insertion into the rectum of the subject. The tube 10 is connected to a gas-tight collecting bag (not shown). The end of the tube inserted into the subject is apertured and covered with a gauze filter and a gas permeable bladder 28."
* Mambo Graphics, an Australian surfwear label, features the iconic "Farting Dog" design [5] in its lineup. Here the flatulence is depicted as a musical note emanating from the dog's backside.
I can't stop laughing!
