Just because I'm like this, I have to mention that I adored checking Daniel's link to a Wikipedia entry. Of course I read the whole thing. My favorite line was this:
Nerve endings in the rectum usually enable individuals to distinguish between flatus and feces, although loose stool can confuse the individual, occasionally resulting in accidental defecation. I bet we've all experienced being the "confused individual". But I love that there's a scientific explanation for how we "know" what's pressing at the door.
From that entry, I found out about Le Petomane, the fart maniac, who was a rave at the moulin rouge in Paris. His acts included singing the song La Marseillaise with his anus, and using his butthole for sound effects in skits and sketches. It's really cool that I found out about this guy because I can do that too. Breathe with the hole and suck stuff in and expel it. I even have witnesses. I'm sure I've written about it. Yes, I have. This guy made a living off of it. Can you imagine going out to see an anus act? What was that movie, I'm sure it was a John Waters film where a guy gets up, rips down his pants and buttlipsyncs Ba ba oo m ow m ow, ba ba oo m ow m ow. I think Divine was in it. What if Cirque du Soleil should think on this. It might fly in Vegas. Or maybe it's all so 100 years ago. Oh my, a thought just occurred to me. What if I'm the Petomane reincarnated? Drawn to a French speaking culture and writing about flatulence. Could be. Could be.
