"Looks like you got an admirer."
"Are you serious? What kind of person writes fan mail to mud?"
"Its not fan mail. You've read 'em, right? These are straight-out love letters."
"Could be worse, I suppose. Think about all the mail for the Joker. All the twisted obsessives, true-crime buffs and murder junkies. Gotta figure somebody out there has a thing for clay."

Okay, now I'm just dying to read Joker's fan mail. What kind of crazy bullshit do you think he gets?
