Howdy. Just thought there might be some interesting places to mine for characters for Poker Night 3.
For example: Farscape. You could get the licence from Channel 9, it's famous enough to be known, obscure enough that the licence is available. Scorpius, Rygel, & Chiana, I think, would make the best choice of players.
From the Valve stable, I'm thinking Dr. Kleiner.
From Adult Swim/Williams St: Nathan Explosion, Master Shake, Cheryl Tunt (from Archer), BraK.
Miscellaneous: Pearl Forrester or Tom Servo from MST3K, Dark Helmet from Spaceballs... Elvira...
Tommy Wiseau. As himself.
