Nipple Ripper Batman
This one takes' some 'splainin'. so, I'll let Warren Ellis do the honors...
Warren Ellis:
It occurs to me that an awful lot of trouble in Gotham City could have been averted a long time ago if Batman had just ripped the Joker’s nipples off.
I mean, treatment doesn’t work, does it? They stick the Joker in the nuthatch, he comes out again and does the same things.
A man with the nipples ripped off him does not make the same mistakes twice...
