This series is great. The two leads act their parts well, but it's most notable for the weird and wonderful ideas that they've thought up. There are lots of really odd, interesting, and most importantly, hilarious sketches. Armstrong and Miller deserve to be better known, as they've created one of the best sketch shows of recent times. This deserves just as much recognition as The Fast Show, Harry Enfield, or Goodness Gracious Me. I saw their live show and it was equally good. Highly recommended.
