Was Larry David more responsible for the funniness of "Seinfeld" than Jerry Seinfeld?

[smoochpooch]

I ask because I have seen Seinfeld's "The Marriage Ref" a couple times and it is terribly unfunny. Additionally, when good ol' Jerry appeared on "The Marriage Ref" and whenever I have seen him as a guest on talk shows like Letterman, all his jokes seem about 20 years old. It feels like comedy has just passed him by over the last 20 years (I will readily admit that his comedy from the 80's has been hugely influential).

Meanwhile, Larry David's show continues to be funny and his appearance on "The Marriage Ref" was one of the show's more refreshing moments. I can't help but wonder if the person who made "Seinfeld" as funny as it was just so happens to be Mr. David. :shrug:
