I absolutely loved this episode. I think I laughed the whole way through! The idea of focussing on the lab rats worked out really, really well! They are all very good actors, and very funny too! Mandy makes me laugh, shame she was only in the first half of the episode. Hodges is just, well, Hodges! Nice to see more of Wendy, I really like her. Henry is a dipstick, but in a cute way! Archie, rawr! Any episode with this much Archie in it is okay with me, he is so cute, this episode is getting replayed often just for him!
There were some very cool lighting effects in this episode; blue at the start of the episode, yellow when the autopsy lights went out. Doc Robbins and Grissom chasing the rat made me laugh out loud, whenever the two of them get together it's a great scene...this one tops them all though!
