Ever wonder how those urban train cars get covered in graffiti? Well, graffiti artists like this guy are the guilty culprits, but usually they work without being noticed. 

This brazen ‘artist’ even put a camera up to record himself working, but was discovered by transit authorities. After being chased around, he manages to escape but first proves just how big his cojones are by running back to get his camera so all of YouTube could later watch the fun.
