maybe i saw the wrong episodes, but brown guys saying "durka durka" for half an hour while the boys run around trying to complete some boring plan is NOT on a level with Chicken Fucker and all those awesome episodes from back in the day!
Overall it has slightly declined from the early years, but just about every recent episode has had something insanely funny in it (and some instant classics in Passion of the Jew and the utter roasting of all things scientology), and of course is still guaranteed to offend everyone.
