I wondered about the no-Snow of Tony today on MTP also.
Was Tony asked to appear and couldn't 'fit it in?'
or was he not asked. Maybe Timmy didn't want to deal with anyone as knowledgeable and articulate as Tony.
But it's an interesting speculation.
Lil' Russ had the evil oil company execs already booked. It seems Timmy never took an economics course in his life. He could not grasp the concept of supply and demand despite how many ways the execs explained it to him.
