Dunno if any of you guys have come across Martymer 81 before, but he is one of my favourite youtube sceptical debunkers. He has produced a number of pretty good and informative videos on a number of subjects including...

And loads more, he can be pretty cutting, but keeps it clear, easy to understand and delivered with a very dry wit.
I really enjoyed his series on Spirit Science and Flat Earth. I think he is very entertaining to the skeptical community but he could benefit from being a little less condescending.
In the second half his vid "Flat out Wrong #6", he has a good summary of the conspiracy thinkers' mindset.
I occasionally remember him and start to watch his Spirit Science series. My favorite's the one where he responds to the guy running that channels' response to his debunks.

I normally lose interest after two videos or so, though. He just doesn't deliver it in a particularly interesting/entertaining way to me.
