There are some really stupid people in this world, and sometimes they do things that can't be ignored. If you live in New York City, you've seen the signs warning against riding on the outside of the cars. If you're like us, you probably didn't believe that anyone would attempt something that dumb. Unfortunately, there seems to have been more and more cases of people injuring themselves or dying from train surfing in the past year. Maybe the signs aren't working, or maybe they're just planting the idea into the minds of daredevils with low IQs. 

Watch as two such idiots go for "some fresh air" across the Williamsburg Bridge late one night via the J train and please, never try this.
