i was thinking about this last night, the disabled guy in the wheelchair once had a scraper and was reliving his joyful sideshow days when he could drive.
either that or hes a homeless guy that knew about the internet site/camera, went to the exact spot and did doughnuts to become famous.
both are plausible IMO
thats literally a little too ridiculous to not have common knowledge of sideshows and/or the camera itself.
