hamilljoker: yeah, wav files of sound clips from the batman tas and batman begins are so damn hard to find. only get the crappy batman movies from the early 90's.
-Quick Edit-
sweet! just did a search and i found a wav file of joker's laugh! hope you like and there's plenty of other quote's there too at SoundAmerica: http://soundamerica.com/sounds/cartoons/Warner_Brothers_Cartoons/Batman_the_Animated_Series/ - scroll down the list until you see the one called "joker.wav"
to everyone: well, since there are only three volumes of batman tas, i sure hope that "Batman: Gotham Nights" comes out on dvd boxset. looks like there were only about two to three volumes. it's made by the same guys. came out in the late 90's. it's the series where the character's looks were updated. for example, black bat on bat's costume, yellow on batgirl's, included nightwing and young robin, pale ivy, etc. also, new look to joker's face. no yellow eyes and red lips. well, to get a better idea of what i'm talking about, here's a link from imdb.com: http://www.imdb.com/title/tt0118266/ . anyways, if anyone knows if this series is coming out on dvd, let me and everyone else here know!
