last week, i went to one of those after-hours museum events, where they keep it open late play loud music and serve booze, so you can drink with your friends and learn stuff at the same time.
i was in the aquarium section of the Academy of Sciences, and staring at this really cool tank of jellyfish. such intricate-looking creatures. these two dudes walk up next to me, and one says to his buddy something like, "oh cool they're like chameleons!" my eyes got really big at hearing this, because these particular jellyfish were translucent - there were lights in the tank that periodically changed colors to red and blue and green and such (like how some cheesy hot tubs have these lights that change colors).
i stood there a little longer to see if he realized what he just said. then i hear, "how do they know to change to the same color at the same time?" waited 5 more seconds to see if his buddy would say anything, which he did not. then i had to leave quickly to get around the corner to start laughing really hard and find my friends to tell them about it. oh man.
