That's all I drink nowdays. I think been (as in, used to be) the manager of a café instilled a secret addicition to a lovely cup o' joe, in me. I don't think it helps that I have a little ritual in which I always have a coffee on the go when I'm writing. But, they do say coffee stops cancer. But ruins everything else in your body. Like your teeth. I remember watching Wife Swap, and these nutters drank coffee through a straw. Absolutely mental.
Recently read The Killing Joke, the 80's Batman graphic novel in which The Joker famously cripples Barbara Gordon (don't worry, that's not a spoiler; it happens pretty quickly). It's not exactly the mind-blowing masterpiece everyone seems to think it is, although that might only be because there have been better Batman/Joker stories since. Taken within context, at the time it was released, I can see it have been a shocking idea.
I like Alan Moore's writing, although he tends to overegg the pudding a bit, especially with dialogue. The Joker is presented incredibly well, but Batman's a bit too "grrr, you'll get yours, you scumbag!". Oh, and the origin of Joker is a bit....hhmmmmm. But it might not be real. Ahhhh! Clever bastard.
