Rather then the smutty stuff his show seems to be well known for, I've been very amazed at the writing and his way with words throughout the first 10 years or so that the show was running. Sadly, later on it seems the focus was more on the slapstick-like sketches, which are still fun, but making the whole show lack a bit of an edge.
