Great dialogue, great jokes and a delightful group of guest actors.
The intro is hysterical! The writer really is funny and the rubber chicken?! And the writer takes a photo with his camera phone! The rest of the episode is just as funny, both as parts of the show Annabelle and from the CSI cast. This was a nice departure from the usual seriousness and often an attempt at a comedy episode in a show as intense as this doesn't work, but it was very well written, the jokes were clever and well delivered, so for me, it worked.
CSI had become a bit stale for me but this was a breath of fresh air. Loved it.
