GrimTheLost: I've not seen the credits for the episode myself, but Wikipedia says that the Rabbit guy was voiced by Scott Menville, aka Robin from
Teen Titans. Which, if true, is bizarre, yet utterly awesome.
Apart from that, it was a good two-part finale, with a genuinely intriguing cliffhanger. For me, this season of
Scrubs has been clearly the weakest yet - the tone's gotten a lot more flippant, some of the recurring humour's getting a little tired, and certain characters (especially Elliot) aren't as likeable any more - but it's still entertaining, and can still throw up involving plotlines. All told, I'm glad it's coming back for another season, but I'm also glad that the seventh season will both be shorter (18 episodes, compared to the normal 22-25) and that it will be the last one. Let's hope they pull out all the stops and send the show off with a bang...
