Captain Disillusion is an Internet show by Alan Melikdjanian who hosts using his alter ego, Captain Disillusion. The show's primary goal is debunking viral video hoaxes. In most episodes, Captain Disillusion will take a modified video which is being passed off as genuine, show what video editing techniques were probably used to modify the video, and then frequently creates a similar video himself using those techniques.
As a skeptic, I feel a duty to point out hoaxes when my friends and family share them. Researching their videos they post online often leads me back to the Captain Disillusion channel, which was how I became a fan many years ago. To this day, I still find myself linking to his past videos when a well-meaning friend is duped by an online video hoax.
