Lachrymatory Memes

Human hubris meets biochemical reality! The poor soul thinks they're immune to onion tears, but doesn't realize that propanethial S-oxide doesn't care about your confidence. It's the chemical equivalent of saying "what are you gonna do, stab me?" to someone holding a knife. The compound is literally a lachrymatory agent—science-speak for "makes you cry like you just watched the end of Marley & Me while chopping onions." Next time, try refrigerating the onion first or wear swimming goggles like my grad students do in the lab. Nature: 1, Overconfident humans: 0.
