I dont know if you knew (I used the 'search' engine and nothing came up, except a coincidence in the word 'fabled'), but in the Fable series of games the main character is able to use many 'expressions' to communicate with NPCs, and one of these is 'fart' (harldy an expression); in the first game you weren't able to choose a female hero, but in the sequel and second sequel you can. I havent played Fable III but I did play Fable II. In Fable II you can 'fail' your expression; doing so with the 'fart' one causes the character to apparently soil his/her pants. The expression can be mantained for as long as you desire, and if you release the button at the right time (succesfull expression) it causes the character to end it with a loud fart. Oh, also, since some here appear to have that fetish too, this can be done as a kid as well (at the start of the game). I saw in a video of Fable III that you can fart in people's faces in that one.
I noticed this as well and was interested.
