Wee Britain wasn't great but it's leaps and bounds above anything in this season.
I think just about everything in this season is funnier than Wee Britain. Even stuff in the weaker episodes: like Michael sharing a college dorm with George Michael and a guy called P-hound or George Sr. taking businessmen into sweat lodges to sell them $10,000 glasses of lemonade. The first few episodes are the worst but they have funny ideas in them. And I think the rest of the season has some gold that's leaps and bounds above a lot of season 3: like GOB's second episode.
