I can hear the conversation now:
Blonde: "OK pal, who's the snitch?"
Joker: "Why so serious?"
Blonde: "Huh? Look, ****o, his is a serious matter."
Joker: "Weeeeeeeeheheheheee!!!"
Blonde: "WTF are you laffin at?"
Joker: "You remind me of my father."
Blonde: "Huh? I'm gonna cut yer ****in ear off, pal!!!"
Joker: "Wanna hear how I got my scars?"
Blonde: "That's it" *grabs can of gas*
Joker: "Wanna see a magic trick?"
Joker breaks free, takes Blonde's gun, jams it up Blonde's ass, and empties it. Joker dances and laughs.
