By now, you would think that Dallas Mavericks owner Mark Cuban would have appeared in many music videos.
However to my knowledge, this is his first ever appearance in any music video. The song is by rapper Dorrough called, "Get Big" which essentially has a billion lines about making money and getting big.
Dorrough, a Dallas native, has Mark appear in the beginning of his video at about the :43 second mark as he leaves an armored truck.
