KING: All right. You mentioned a sense of humor. Everyone who knew Al Gore for years knew he was funny. Why wasn't he funny on stage? WALTERS: There is something about the way he talks that is earnest and maybe slow, you know, that even when he's funny somehow you don't realize it. What he's been saying now, when he was campaigning for candidates, he has a wonderful line, which was, "I'm Al Gore. I'm the man who used to be the next president of the United States." You know? Wow, what a knee-slapper. That Al Gore has some quick wit! (/sarcasm)
