Oh good, so it's not just me. I haven't watched the last few seasons, for the most part, because the episodes I have watched were mostly bad. They still have some good humor, but the funny/bland ratio is worse. Also, the last few seasons a lot of the pop culture references are to things I am unaware of, so that may play a role (then again, I didn't know who Barbara Streisand or Alanis Morrisette were, either). The human centipede episode stands out as being very gross with little humor.
