Telltale made lots of short movies to promote Season 1 of Sam and Max, right? 3 per episode or so. And Valve have lots of experience making hilarious, entertaining videos based on their Team Fortress 2 classes.
I'd like to see some short movies based on Poker Night, because we all know they would be great.
For instance, FAILED PITCHES FOR POKER NIGHT CHARACTERS.
Sam, Gromit and the TF2 Guard Dog play poker. (actually that would make a good picture)
"So you guys smell anything good lately?"
I think it'd be a good way to make some gags without writing pages of dialogue for characters. Maybe that's just me, though.
