"What's that smell?"

Alternate title: "He who smelt it, dealt it."

It’s a cliched act of common courtesy to light a match after using the bathroom (or more specifically, after dropping a dirty bomb on Mount Porcelain). But how does that actually combat the stinky memories left behind by our behinds?

By producing a smell that’s even more pungent!
During an episode of MythBusters, the hosts pumped hydrogen sulfide and methyl mercaptan (smell-causing compounds that are found in both farts and feces) into a sealed chamber. They then measured the concentrations of these gases before and after lighting a match, and found that the accumulation of gases remained unaffected. This proves that lighting a match doesn’t either consume or eliminate these odorous compounds.
Instead, lighting a match produces sulfur dioxide, a smell-causing compound that’s even more pungent (and way more agreeable) than methyl mercaptan. “Sulphur dioxide smells completely different [than methyl mercaptan] and is much less unpleasant,” Jo Døhl, head of the Department of Chemistry at the University of Oslo, explained to ScienceNordic.
In other words, the odor-causing compounds found in farts and feces are still present after lighting a match, but they’re disguised by the potent smell of sulfur dioxide. Most of the time, in fact, that’s enough to cover the smell altogether (and if it’s not, we recommend visiting your doctor in the near future).

That's what I always thought anyway?

Isn't this one of the theories as to the development of perfumes? To cover unpleasant body odors with something more penetrating, but less unpleasant.
