On the first episode of the Colbert Report, Stephen Colbert reintroduced "truthiness" to the world.

As defined by the Macmillan English Dictionary:

truthiness noun
the quality of stating facts that you believe or want to be true, rather than stating facts that are known to be true

Any videos stating,showing or blowing the whistle on blatant falsehoods are welcome here. They can be anyone, politicians, television personalities, celebrities, etc.

Well then, start hunting for videos!
