I'm always unsure whether or not to recommend All-Star Batman. It's really, really bad, but it's also kind of hilarious. So I'm like, "Read it! It sucks a lot! " and then people get confused.
Anyway, here's the original image. Now, I'm not a Batman expert or anything, but I don't think Batman would ever say "retarded."
What I enjoy about this meme is that various writers have incorporated it and made fun of it, much like how everyone makes fun of Rob Liefeld now (which will come later). Like Gail Simone in Birds of Prey:
My favourite instance of this meme is in an issue of Superman/Batman. Chibi versions of the Justice League are let loose in our world, and the little Batman is just as angsty as his big counterpart.
But poor chibi!Batman doesn't get to even finish the sentence. Big Batman is thinking, "Goddammit, it was ONE TIME, and no one ever lets me forget it!"
Another example of writers being aware of their audience is when they make fun of Rob Liefeld, which is pretty much all the time.
From Fabian Nicieza's Cable/Deadpool, this isn't strictly an example, but everyone knows that Rob Liefeld loves his pouches. He can't not have been thinking about Liefeld when he wrote this.
From (I believe) Jimmy Palmiotti's run on Deadpool, we have the two old ladies who offer Deadpool the use of a very big and complicated gun called the Liefelder.
And most blatantly of all:
On Daniel Way's run on Deadpool, he actually turns and addresses Rob Liefeld, making fun of his obsession with pouches.
