Only person aloud to break 4th wall in DC is Star Boy and Lobo other wise I get pissed 

I think he might've broke the 4th wall at LEAST once. Says so in one of the online bio's (if not here, then try wikipedia. or dc database.)

And occasionally Deadpool or She-Hulk. "

This is in Rogue forum why?

I'm struggling to comprehend how & why this was put in the Rogue forum :p

Joker is prone to showmanship related bravado.
 
The only DC character who is aware that he's in a comic book (not necessarily 4th wall style) is Ambush Bug.  Bug can even see the 'floating head' that is used to suggest Firestorm's collective mind.

He breaks the 4th wall and addresses the reader directly in the Joker's Asylum series, but that isn't unique to him. He does crack the 4th wall from time to time, but I don't think he's aware of it. Like he'll say something that has to do with actual reality but isn't showing any kind of ability to comprehend that he isn't in actual reality.

I'm pretty sure he's comprehending it when he grabs his own speech bubble.

He does break it, but only insofar as a way of being a narrator. He doesn't break it in the context of the story. So he more bends the fourth wall.

And back in the 70's in Detective Comics "The Sign of The Joker" and "The Laughing Fish" story line, he had a whole page of stepping up to speak directly to the readers and even turned the page for you as he bowed and tipped his hat. In his own run of comic books he spoke directly to the reader. There was also an annual or some collection of short stories, wish I could remember the issue, where he hit the nail on the head. He looked directly at the reader and talked ot them and explained he knew we were here. that he does it for his fans and appreciates us, cause we get him. He also says since he is the only one in the book who knows it is all just a story, he gets The Joke. Where as the other don't.
I'm going to have to dig that issue up so I can quote my source.

It seems to depend on the writer.

If he did he would be breaking the 4th wall like Deadpool.

 
Please excuse my ignorance, but, where exactly did the Joker grab his own balloon (no genital pun intended)? And has this happened more than once? 
 
[I am wondering purely in what regards the comics, not other mediums, i.e. animation, live action films, etc] 

im with christopherwalken ive totally missed the part where he grabbed his own speech bubble..?

I'm sure this will put all ambiguity to rest:

I think flipping the page for the reader is a solid "yes".

I just thought he was crazy. Hope he doesn't that will destroy DC. That important of a character knowing its all fake would be horrible.
