Highly rEsteemed!

I've often wondered if there was a really good "Subject" to use as an example of Cognitive Dissonance and Bias. Whereby the "Subject" could be seen to have an argument with Themselves through the use of several videos that the "Subject" provides openly. A great "Subject" would be someone who almost consistently displays his own hypocrisy while bragging about it in other videos... Any ideas on some "Subjects?"
