You have to find a copy of Oni Press Color Special 2001 -- it's fucking hilarious! Bendis wrote the major story, and it features both Walker and Pilgrim (from Powers) as they investigate the death of Madman.
Bendis takes every opportunity to poke fun at the indy scene, The Big Two, other creators, and even himself. For instance, he has Oeming do the repeated panel thing 27 times on one page, and then, well... just read this dialog:
Pilgrim: Yes. Round them up.
Walker: Yes.
Pilgrim: Yes.
Walker: What?
Pilgrim: What?
Walker: No, what?
Pilgrim: What?
Walker: Why are you repeating everything I am saying?
Pilgrim: Why am I repeating everything you are saying?
Walker: Why are you repeating everything I am saying?
Pilgrim: Why am I repeating everything you are saying?
Walker: I'm asking you --
Pilgrim: You're asking me? You're asking me?
Walker: Yes.
Pilgrim: What?
Walker: What?
Pilgrim: What?
Walker: Huh?
Pilgrim: What?
Walker: Yes.
Pilgrim: Good.
Walker: Uh -- let's go.
Pilgrim: Let's go.
Walker: Stop it.
Pilgrim: Stopping.
Walker: I mean it.
Pilgrim: You mean it.
