Farting is funny. Smoking is not. That's the dynamic which fuels this amusing spot from the Ontario Ministry of Health's "Quit The Denial" campaign in Canada. The bit follows a woman from her shrink's office to a party of flatulent friends to show how her farting becomes an addictive crutch. Titled "Social Farter", the ad is rather, um, long-winded, requiring nearly a minute of passing gas before revealing its point.
