This one hurts about as bad as celebrity deaths can hurt.
There have been many great comedians, but there is often an overlap in styles. Norm was a comedian unto himself, someone who seems kind of impossible to replicate.
There are too many videos to post, but it's easy enough to lead with this all-time classic.
Oh ****, that really sucks. He certainly hasn't been prolific lately, but it's sad knowing we'll never get another random Norm interview or youtube series.
This clip, when Norm gets emotional sending off David Letterman, has become even more poignant with the knowledge that Norm was already dealing with the cancer that would eventually do him in.
Norm seemed to be sincerely flummoxed that animal hospitals were a thing that exists. It's like it escaped his notice that veterinarians were a thing. Not a Leno guy, but I love Leno's tickled reaction as he tries to interject that of course he knows about animal hospitals.
The Seinfeld episode with a plot that mirrored this bit aired after this interview, so it seems like he may have worked up a bit here that gave rise to its own Seinfeld plot.
