I used to believe that while on holiday in Spain, i had seen the red and green man at a pedestrian crossing fight each other, and would tell people about this whenever the thought entered my head until i was about 5. That was only because i again saw whatever film that scene appeared in (i think Superman 1 or 2), and realised my utter stupidity.
