Oh, this is fantastic.
We don't exactly know who "Mike" is, but he apparently owns a Golf Shop in the Chattanooga, Tennessee area and he spared a LOT of expense creating his own ad for the Mike's Golf Shop.
Check out the video, which is going to, if not already, make him famous. Maybe not in the way he intended, but in a viral video kind of way.
And yes, it appears he shot the video with his cellphone.
