Slowly, the lights begin to dawn in Mingo's recessed mind...

Mingo:
"Wait a spell... now I reco'nize you! You're that no good Obadiah Dirt that gunned down my three brothers! Two of them boys didn't even deserve it!"
 
    Obadiah:
"No, that ain't true! My name is p-p-p-Pupkin..."
  Mingo:
"So... yer in jail under a phony name, huh? Won't it be fun to watch them find out about who you are? I can tell 'em about them Marshals you done killed, too... It's just too dang bad yer trial is going to be post mortem!"
