Quote from : Batman: Mask of the Phantasm Movie

[while Reeves is trying to resist the effects of Joker's toxin, Batman appears in his hospital room]
Arthur Reeves: [gasps, then giggles helplessly] Oh, no!
Batman: Why did the Joker meet with you?
[Reaves keeps giggling]
Batman: It has to do with the gangster murders, doesn't it? He thinks you're involved. WHY?
Arthur Reeves: [giggling] I don't know!
Batman: [grabs him] That's not the answer I want!
[Reaves manages to calm down]
Arthur Reeves: Beaumont needed me to help him and his kid get out of town...
[starts to giggle again]
Arthur Reeves: He kept in touch.
Batman: When was the last time you spoke to him?
Arthur Reeves: Years ago, my first election campaign. I was running out of money and I asked him for help...
Arthur Reeves: He said no!
Batman: So you sold him to the mob.
Arthur Reeves: [now laughing hysterically] I was broke! Desperate! They said all they wanted was their money back!
[he collapses with laughter, as Batman leaves in disgust]
