In the TAS episode with Joker and garbage (The Last Laugh I think it is) almost everything he says is funny.
Joker- You killed Captain Clown... YOU KILLED CAPTAIN CLOWN!
Joker- Batman! You wouldn't leave me here to die, would you?
(Batman is seen enjoying himself)
Joker- BATMAN!!! (in a whiny voice)
And just another random quote, Joker's Million's I think
Joker- Well drown the kids, and shoot the neighbors!
