This is the third episode Try This, the show where Gary and Kole impose media on each other. Each episode has two sides, each dedicated to a different work.
In part one, Gary has Kole check out Grant Morrison's comic mini-series The Filth, a psychedelic and thoroughly unpleasant work that explores a lot of Morrison's pet themes. This one isn't for the faint of heart.
In the back half, Kole has Gary look into The Gunslinger Born, the first comic adaptation of Stephen King's The Dark Tower series. It adapts parts of book 1 and book 4 into a good introduction to Roland as a character, and the world of the Dark Tower.
