George Carlin and the Truth about American Pride and God's Blessing
Always speaking his mind and telling it like it is, no matter the venue or subject, his performances grew more and more like political speeches, as his wisdom grew with knowledge and experience over the course of his career. Fart joke heavy performances in smoke-filled comedy clubs of the 70's eventually became arena-filled exposes of truth and political enlightenment.
As they say, the best "comedy" is always rooted in truth. @Conspiracy_X
