“If you tell a big enough lie and tell it frequently enough, it will be believed.”― Adolf Hitler

Just in case somebody starts quoting Hitler in attempt to appear sophisticated, this quote is actually misattributed. Moreover, variations of this quote were actually said by Hitler and Goebbels, but about the Jews and anti-German propaganda, not themselves (see big lie). Indeed, why would Hitler say anything incriminating himself publicly enough, so it could be quoted much later?
