Have you ever run into someone, on the subway, perhaps, or in line at a Starbucks, and noticed they’d forgotten to close up the zipper on their jeans or had their skirt tucked into their underwear? Inner conflict follows as you weigh the pros and cons of telling them about it. On the one hand, that person is almost certainly going to think you’re a jerk for pointing out their social faux pax, but on the other hand, you’d be saving them the untold awkwardness of interacting with everyone all day with their underwear half sticking out of their open fly.
There may be a good middle-ground solution though, according to one Japanese comedian: Just tell them what you want to say with such a thick accent that it sounds like a totally foreign language. Sure, the person on the receiving end will think you’re a huge weirdo, but at least they won’t think you’re an A-hole, and being confronted with a bunch of unintelligable jibber jabber from some random will probably cause the person to take a quick inventory of their surroundings, hopefully prompting them to realize their zipper is down or underwear on display.
