Norm had an awesome bit on if you have cancer and die you win the battle because you killed the cancer. His delivery on all of his jokes was genius. Really hurts to lose him.
Its almost like an entire genre dies with him because no one can copy his style or delivery.

One of my favorite Norm moments ever:

“In a brilliant move during closing arguments, Simpson attorney Johnnie Cochran put on the knit cap prosecutors say O.J. wore the night he committed the murders. Although O.J. may have hurt his case when he suddenly blurted out 'Hey, hey, easy with that, that's my lucky stabbing hat!'”

I love how you can tell Norm legit makes Seinfeld uncomfortable at 0:18 and then knocks it out of the park with his spin on it. Genius.
