I used to go out to nightclubs quite frequently when I was younger, and since I lived in New York City and San Francisco and Los Angeles, there were a lot of really fun ones. But even a lot of the fun ones would do the same stupid thing that made everyone look awful: light areas with black lights. With black lights, everyone's dandruff glowed and stood out, every piece of lint became visible, and every bit of oil in everyone's pores took on this otherworldly luminescent quality. But by far the worse thing the black light did was to make everyone's teeth glow these hideous colors of neon yellow and green. It was positively revolting! (White, however, would glow perfectly white, whenever it appeared on people's clothes. Unless it was leather, or synthetic stitching: that didn't glow so much no matter how white it was, for some reason.)
Well, this scenario has always made me think of the Crest Whitestrips, or the whitening toothpaste, for as long as I've known about it, because if your teeth really were absolutely white, in black light they would probably look amazing! But the fact is, most people's teeth aren't perfectly white, so they would glow bright highlighter-pen yellow or green (and their plaque would stand out really yuckily too). And that's why I think this dance club scenario with the black lights would be so great for an ad for a tooth-whitening product. And it would be really easy to show it, too: Simply show three or four people dancing in a dance club with black lights, and then they smile at each other (maybe laughing about the glowing lint or dandruff), and all their teeth are yucky looking, glowing yellow and chartreuse and lime green, and they notice and start to feel self conscious, so they hide their teeth behind their lips (being pretty obvious about it). But then, someone else they know comes bouncing up to them and smiles a big toothy grin that is absolutely perfectly white, and it makes everyone glow like a key light is on them, and then the announcer could say: "Stop hiding your smile! Get your teeth their absolute whitest with Crest Whitestrips!"
