Agreed. The show is often very good, but Penn insists on cheapening it with pointless, adolescent profanity and gratuitous T&A for no good reason. That's why I don't watch it much anymore. It's not offensive. It's just lame.
Their show would be so much better on regular CBS where they would be forced to be creative instead of just sticking F words where the jokes should be. I think because they are on Showtime they feel obligated to do this over the top schtick just because they can.
