(S08E04) This week we're back to the case and off the personal issues of the detectives. And the case is particularly disturbing. A single mother and her 10-year old daughter are found bound, raped and murdered in their apartment. The initial suspect is a very dirty, mouthbreathing Jerry Lewis.

Lewis really stole the show, didn't he? He was heartbreaking as a man who was so depressed that he became demented. He ended up being Det. John Munch's uncle who came up to NYC from Florida in June to see him but forgot what he was doing and ended up on the streets. He experienced a remarkable change in personality. Basically, he turned from crazy homeless man to, well, Jerry Lewis. And then he changed to crazy Jerry Lewis.
