I've seen James "The Amazing" Randi perform twice and I read his book, "Flim-Flam."

His is a good story.

I'm aware that frauds have sued Randi. News to me, though, was a line from the above wiki article. Randi claims to have "never paid even one dollar or even one cent to anyone who ever sued me."
