[How did I fail to notice how hilarious this line from issue 7 is? Thanks you James.]
I wanted to mention something from All-Star Batman #7 that lept out at me, but I haven't seen picked up on. Batman mentions someone who can fly, and "the idiot doesn't even know he can". I thought that was a great line akin to DKR's "why do you think I wear a target on my chest"? It offers an explanation for the first Superman comics where he couldn't fly, and simultaneously paints Batman as such a badass that he knows more about Superman's powers than Superman does.
