Mercurial Denver Nuggets guard J.R. Smith uploaded this picture of his insane new neck artwork to his Twitter account.

Smith, nicknamed "J.R. Swish" for his proclivity for snapping the net on his jumpers, has long been among the NBA's league leaders in ink.  But this?  This is a whole new level. 

Take a look for yourself...

It's hard to know how to react because he's reaching virtually unchartered body art real estate.  I do think it's fair to say Smith is now the owner of the fanciest little Adam's apple ever.
