Oh I love this comic much, so fantastically written. The thing I love about Dan Slott is his great humour, especially when it can so quickly turn to disgust, horror or something else. Humpty Dumpty is an awesome character too, I wish we would see more of him, though he was seen in the recent Arkham one-shot so that was cool.
Regarding the scans themselves (thanks for posting seawolf too) I funnily enough never got the "body gag" until about the fifth time reading (I always go through my comics every now and then, always) and then I was gobsmacked!
The only bad thing for me was Two-Faces interpretation, he flicked the coin for everything. Joker was absolutely brilliant though, well done on the artist for that.
Personally I think this is THE Arkham book to buy that will scare your pants off, it beats Serious House by a country mile for me.
