Bart's class gets a new teacher, Mr. Lassen, who is really nasty and cynical. Bart cooks up revenge for Lassen, as intended to embarrass Lassen at The Blazing Guy Festival, where Lassen is selected to fuse a giant statue, so the whole family and Milhouse travel to the festival.
While the Simpsons guest voices come and go, I might even argue that Dafoe's Lassen, is one of the best modern-time Simpsons guest voices. In fact, I liked a lot of his voice role, which executed a suitable bad temper.
The episode is good. BG-festival event is a fun place to get out jokes. The festival's bizarre things alsogive the episode new creativity, which was also refreshing. Each character reacts differently to the festival. Marge accidentally use drugs, and goes to a trip. Bart and Milhouse try to embarrass Lassen and Lisa and Homer and feel that they are at home.
Blazed and Confused is a fun and creative episode, which is crowned by Willem Dafoe's great voice role as Lassen and fun of the Blazing Guy festival, where the characters are well suited.
