I thought that this was relatively settled but now there seems to be a resurge in speculation so I figured that we could all air our expectations/desires regarding the Joker's smile. Is it going to be the result of some sort of accident after an encounter with Batman; is it going to be mob revenge; self inflicted? Personally, I'm for any of these except for the accidental thing. It seems a bit coincidental for him to accidentally get scared across the mouth, esp when he has a thing for clowns.
