Everyone farts. Even that virginal cheerleader you had the crush on in high school began her day with a triumphant blast of her trumpet. It's a fact of life as stinky and socially irrelevant as The Facts of Life, and to us modern hepcats we can't see anyone making a big deal out of it.
But (ha ha) farts have had an uphill climb to gain mainstream acceptance. George Carlin famously added the term to his trademark list of dirty words that you were not allowed to say on television, and for a long time he was right. There was little flatulence heard or discussed on network television. In 1957, an episode of Leave It to Beaver involved a heavy round of propriety discussion over just showing a toilet tank, so it's understandable that society has taken awhile to just enjoy a good fart. Nowadays farts are on rise, and even video games have gotten in on the act.
