Reminds me of the time I came home at 5:30 AM to my apartment in center city Philadelphia and saw a bread roll neatly tucked under the windshield wiper of every car parked along South Street. Nobody seems to know this, but the bakery that makes the rolls for all those Philly cheesesteaks just dumps transparent plastic bags full of rolls on the sidewalk in front of each restaurant in the early hours, and some wag just decided to put them to better use. I'm genuinely surprised I only saw that once.
