During my senior year in college I attended a laser safety seminar at LBNL. I didn't actually work at the lab, but they had free danishes and, you know, you might meet someone.
The seminar consisted of tips and rules for safely operating lasers, like "Don't point it at your eye," "Don't point it at other people's eyes," "If you're going to burn off a mole wear goggles," and "Always turn on the 'laser on' warning light, because unlike those fancy bastards over at KALX we don't have the technology to make that happen automatically."
The seminar concluded with a look at laser hazard signs from around the world. They all had the same graphic (an eyeball on fire), but each said "Danger: Laser Radiation" in a different language. As the instructor put each sign on the overhead, he'd ask what language it was in, and we'd call out our answers. "German!" we'd cry. "Portuguese!" "Korean!"
Finally he put up a sign written in curvy, jagged letters and dots, and asked if anyone knew what language it was in. Without really thinking about it, I found myself saying, "Klingon?"
And it was Klingon. Now, I am not now, was not then, and have never been what you'd cal a Star Trek fan. But somehow I managed to identify the Klingon laser hazard sign using the sheer force of my own innate nerdery.
The point is this: If you're at a laser safety seminar, you're a nerd. If you're at a laser safety seminar and manage to spot the random Star Trek reference, you're a giant nerd. If you're in a room with eleven Physics majors and you're the first to catch the Star Trek reference, you're the giant nerd that the other giant nerds and smaller nerds bow down to as their king.
Of course, there was no actual bowing that day, but there were a lot of genuine oohs and ahhs, and I got a plush eyeball as a reward for being the "Klingon Warrior."
