Not exactly a story, but a picture thread on Reddit where a guy posts a photo of his tattoos on his arms, and someone goes “how did you take this picture”, so he posts a selfie showing him balancing a phone on his shoulder, and someone replies “wait how did you take that picture” and then he posts a photo of him taking a photo of him taking a photo… and this continues until he reveals multiple complex camera setups. Such a legendary thread.
