Richard M. Nixon was the 37th president of the United States, serving from 1969 to 1974. He is the only U.S. president to have resigned from office.
Famous for telling reporters, "I am not a crook," Nixon once gave this advice to a political associate: "You don't know how to lie. If you can't lie, you'll never go anywhere." Nixon couldn't cover up Watergate and he couldn't cover up bloopers like that either.
