The Nike correspondence was quite amusing!
The only urban legend that springs to mind was short-lived in terms of time and place I think:-
Every year the city I live in has a carnival. Streets are packed with spectators waiting to watch the parade, which is so elaborate it takes about half an hour to dance past, with trucks blaring music, draped with girls throwing out sweets, snacks and other free publicity. It's a lot of fun, although one year a rumour went round beforehand: a guy is going to be in the crowd with a syringe of AIDS-infected blood. He's going to go around jabbing it into people while they are straining to see the parade.
In the end, not true, afaik.
