the way I borrow a friends car and always tell them I farted in it right before I got out as I hand the keys back. It’s never true, but I wonder if it would stink hours later if it were. (yes ladies I’m single. Can I borrow your car?)
a story I heard when I was around 10. Supposedly a high school girl farted in a jar and closed it, then waited a week or two before taking it to school and releasing it into the wild. It was quite pungent, according to the story, and I always wondered if the story were true/possible.
the Sarah Silverman program where her two neighbors find a jar which one of them had farted in years earlier when they first moved there. This led to them trying to get each other to inadvertantly smell contained farts and culminated in one of them duct-taping the bathroom door and filling it with farts through a hose.
Of course, even if the sulfur compounds decayed into something else, most sulfur compounds are pretty aromatic (or rather, ugly aromatic). So it might not still smell like a fart, but it’d probably still stink.
