Ok according to wikipedia these are the first seven episodes they'll do, in order.
War on Porn
New Age Medicine
Sleep Inc. (probably mattresses and some sleeping pills and maybe those learn while you sleep things)
Sensitivity Training (a great topic, worthy of BS)
So that leaves 3 left. I hope they tackle sex offender laws (any law that treats streakers and mooners like real rapists is serious bs) and violent video games, I really don't want to have to wait till season 7 to see them.
