Stocking, on the other hand, has a ton of potential for variation. The world of stock photos is vast and strange, and the juxtapositions of stock vs. original photos can be hilarious. Some show how absurd a certain pose would look if people actually tried it in real life, while others highlight the strangeness of a world staffed entirely by people who look like professional models.
