A very Thunder Halloween Part II: Check out the costumes of OKC's players

As is becoming tradition right before each season, Nick Collison threw a birthday/Halloween party on Saturday night.

Last year, Serge Ibaka stole the show by dressing as Akeem from Coming to America, which you can see by clicking here.

This year, the costume champ was probably Russell Westbrook. Complete with a full mustache, Westbrook dressed as the cop from popular TV show Orange is the New Black.
