Why does John Batchelor (the talk show host) say that he's "the great American"?

I tried to have the T and the G (The Great American) lower case.

WHo is John Batchelor and why would anyone take anything he says seriously?

@elbanditoroso What about the link I posted? About:

Do you mean anyone who says “I’m the great American” shouldn’t be taken seriously, why is it?
I believe we try to prevent heart attack because we take it serioulsy, right? Not to say as bad as a heart attack or something like that.

…Edited link just above.

Is it just because it’s bragging, plus plus, or something else too?
