Geraldo Rivera offers a $10,000 reward for anyone who can find evidence of a case in the United States where somebody is under oath saying something unrelated to their actual case. But apparently, nobody could find a case in American jurisprudence where somebody was tried for perjury for just having sex with his secretary.
