I had a customer tell me that in either the pre or post crisis DC that Joe Chill, the thug that killed Batmans parents ended up turning into the Joker... I have NO recollection of that...

In the continuity that I thought was current, Chill killed his parents... and in Year Two and the follow up, was murdered by the Reaper.

Any idea which one is current? Or if the guy was just nuts and thinking about the sucky ass first movie with the first bit about the Joker?

Anyone?
