It's been flagging a bit recently, but these episodes were made at the height of The Simpsons' scurrilous powers, in the mid-2000s.
It's all about Homer, of course, but it's the more peripheral characters that bag the best lines, such as Mr Burns ("This is an outrage. Since when are public figures fair game for satire?"), and the unhinged Groundskeeper Willie ("Oh my God, I've shredded a child. Again!"). Simon Cowell, Tony Blair and J K Rowling are among the guest voices in these droll, wildly inventive episodes.
