This is actually the second time I've read this story, but for some reason I didn't remember much of it. Alan Moore has written an origin story of sorts for The Joker, and with the help of some utterly stellar art by Brian Bolland, he's painted a picture of a character who is the very embodiment of insanity. I love how quickly The Killing Joke moves along, without wasting any time. Moore's Joker dialogue is perfect, probably the best I've ever seen for the character, weaving in and out of punchlines and deranged rantings with an ease that only seems possible coming from a maniac. The plot is shocking, the character work surprisingly human, and the art some of the most iconic in Batman history. This is a must read for sure.
