4. Chef
'Hello there children.'
We all remember those years when the boys could run to Chef with their problems, and although those days are behind us, we can look back and remember Chef fondly. Whether it was giving wildly inappropriate answers to the boys questions or suddenly breaking into a serenade for an attractive female, Chef regularly stole the show. Chef was always an incredibly loveable character, if for the wrong reasons. In fact when Issac Hayes left the show, the writers found a way to keep Chef in for one final episode. In the first episode of season 10, 'The Return of Chef', Chef used only stock dialogue and has left South Park to join the Super Adventure Club. The boys go on a quest to un-brainwash Chef, a process that has a rather icky result. It all has to do with a sharp rock, a long fall and some mountain lions. Goodbye Chef, we miss you.
