You all saw the dance
One of Hahn's sponsors, Travis Mathew, has made a special edition shirt titled "Ganghahn Style" -- a clever nod to the Gangnam Style pop song and its well-worn dance.
You can snag one for the (not very low) price of $39.99.
Here's a snapshot of the shirt.
The dance is great and all -- in fact, Hahn's story is pretty great -- but I bet he wishes people would remember him for something other than a silly dance in a tournament he didn't win.
