There is such a thing as reckless and there is such a thing as stupid ... Justin Bieber riding his skateboard while hanging onto the side of a moving van is the latter.Biebs -- who of course had a friend film the stunt -- posted the video on his Instagram page on Saturday with the caption, "Ridin down fairfax lol had a great time."
As the old Eminem lyric goes, "How the f*** you supposed to grow up when you weren't raised?"
