A redditor called Frankie842 snapped a photo of a public hair stuck to a urinal in a near-perfect treble clef. I once experienced something like this, back when I was roomming with Possum Man. We’d cooked a pot of spaghetti and we tried the technique of tossing a strand against the wall to see if it would stick. It landed in just this configuration and we left it up on that wall for years after.
