While I can't watch most of his movies today, there are still bits I laugh at. Once upon a time I loved his and Dean Martin's movies (together and apart), along with those of Abbot and Costello, Laurel and Hardy, The Marx Brothers, The Three Stooges...
Not familiar with his work personally, but I can't deny his legacy and influence on Western pop culture and comedy. I couldn't guess how many times in cartoons, and various other mediums I've heard characters whose voice and mannerisms were clearly modeled after him (for example, an episode of Batman: The Brave and the Bold I was watching just this past Sunday) May he rest in peace.
His legacy that will always live with me:
"a-ah, pretty lady!"
I'm sure he would hate that.
My favorite Jerry Lewis movie is The Geisha Boy, written and, I think, directed by Frank Tashlin.
Harry is obviously related to Bugs Bunny...
