That's amazing. My closest story is similar to this actually. I have a couple of friends who have a photobombing hobby, to the point where they're the equivalent of world record holders for it (and turn it into a charity thing), (what they're known for when they're not spelunking). They know all the hotspots for it and whatnot. It got to the point that facial recognition would go haywire, even though it's only when they're together that they're unmistakable, while, individually, they're quite generic for spottable people. So anyways, a few times I might have been looking at pictures somewhere like a dictionary or maybe footage, and at first if I think "oooh this looks exotic", there they are in the background, peeping out from behind a fence or something. Most endearing part is I made myself my art hobby separately from this or knowledge of it, and it intertwines.
