If you don't you really, really should. We briefly touched on it way back when but it was buried in an Introduction thread so you may not have seen it.
There's a guy who tweets as God_Damn_Batman.
Here's some examples of his wit and wisdom:
"I love the little New Year's Eve traditions: The ball drop. Joker timing a bomb to it. Then me beating him until he talks like Dick Clark."
"Anyone else keep getting that "Let the Bodies Hit the Floor" song stuck in their heads while clearing out warehouses full of mobsters?"
"What has four eyes but cannot see? Answer: A glasses-wearing Riddler after I beat him into a coma. Also would've accepted "Mississippi.""
"In my darker moments I despair over the injustices I will never be able to stop. Greed. Hunger. Plague. The Jersey Shore."
"No Alfred, I don't have any idea how Shady Acres Retirement Home got programmed into speed dial. Now about that sandwich. Chop chop!"
"Launched a new charity to help keep ex-cons off the streets. It's called "Stay Off the Streets or You Get Beat in the Face with a Batarang.""
Go here and revel in the laughter!
