Jerry Seinfeld: It's 98% in how you deliver the joke

Here's Jerry Seinfeld talking with George Stephanopoulos (who, you may recall, had been White House Communications Director under Bill Clinton) about comedy. In his new Netflix special Seinfeld returns to the oldest jokes in his repertoire. Starting at about 2:28 he talks about he had to relearn ALL of the old bits, which he illustrates with one about cotton balls.

Stephanopoulos: It's not just what's on paper?
Seinfeld: No, no. That's...two percent of it. 98 percent is the way you do it.

There's a shot in the special where we see all the yellow pads on which Seinfeld crafted his jokes. We see that shot in this little clip.
