Aha! Now we know why womens farts never smell as bad:

"The odor of farts comes from small amounts of hydrogen sulfide gas and mercaptans in the mixture. These compounds contain sulfur. Nitrogen-rich compounds such as skatole and indole also add to the stench of farts. The more sulfur-rich your diet, the more sulfides and mercaptans will be produced by the bacteria in your guts, and the more your farts will stink. Foods such as cauliflower, eggs and meat are notorious for producing smelly farts, whereas beans produce large amounts of not particularly stinky farts."

"The longer a fart is held in, the larger the proportion of inert nitrogen it contains, because the other gases tend to be absorbed into the bloodstream through the walls of the intestine."

"Do men fart more than women?
    (Submitted by Bigdude)

    No, women fart just as much as men. Its just that most men take more pride in it than most women. There is a large variation among individuals in the amount of fart gas produced per day, but the variation does not correlate with gender.
    I have read that men fart more often than women. If this is true, then women must be saving it up and expelling more gas per fart than men do."

PMSL at that last one !!  :mrgreen:  :mrgreen:

LOL Serious, I love that you feel the need to tell me how farty women are - funnily enough I know full well

Is it possible to leave a brown spot on your pants because of a fart, and if so, what causes it?
    Judging from what I see when I do the familys laundry, Id say that the answer to the first question is definitely yes.
   As for the causes, we must remember that what we call "fart" and what we call "poop" are just end-members of a continuum. That is, we can have a pure fart, or a pure poop, or anything in-between, depending upon the admixture of the two.
   If a sample consists mostly of poop with only a small fart component, you get such things as jet-propelled bowel movements and spongy, floating fecal masses (you know, the ones that refuse to be flushed down the toilet -- they keep popping back up).
   If the sample consists mostly of fart with only a small poop component, you get what is known as "skid marks" or "fart art." These can also result from inadequate wiping, but the shape of the stain is different in the two cases.  Inadequate wiping leads to elongate marks parallel to ones crack, usually with well-defined edges, whereas fart art is generally more circular and has an air-brushed look.

PMSL!

It looks like the suns corona.
