Just when you think you've seen every incarnation of every dunk possible, along comes another stunning video like this one.

Below you'll see Porter Maberry throw down some rim-rocking jams that are impressive in their own right. The dunks are made even more spectacular by the fact that Maberry is just 5-foot-5. That's right, this guy is four inches shorter than Nate Robinson and two inches smaller than Spud Webb.
