Sometimes GIFs are so bizarre, so creepy, so surreal, that it's a good idea to only watch them once. Because after too many viewings of certain GIFs, the walls of reality start to break down "Inception"-style and you start to question whether or not this is in fact real life. But there's obviously a problem with that. GIFs are inherently on a loop. To watch a GIF only once would take some impressive dexterity with the command W shortcut (Mac users, baby!). But the way we see it, that's your problem. We're presenting you with these GIFs you should watch only once because it's an important public service. How you're actually going to go about watching them only once is something for you to figure out.
