Previous seasons: one, two, three, four, five.

The writers continue to mine humour by distorting the behaviour of the characters and humiliating them. They occasionally manage a funny joke, although not enough to keep me watching. The highlights are the cameos - Stephen Hawking and Bob Newhart that I can remember. It's painful to compare this to the brilliance of the first two seasons, and I don't want to think how poor it got by the 12th season.
