I don't think this was "who's the better billionaire for the world" but rather "who's the best billionaire period?" And though Bruce Wayne gets my vote due to that he really tries being a good billionaire overall, I can see why Scrooge wins.
Scrooge did gain his fortune, and though he is a greedy duck- he does have more then Bruce Wayne does I know that for sure. Not to mention that quote "a duck on the moon *laughs*" got to me good, I was laughing quite a lot from it. Well played.
Maybe for next week's debate, you guys can do the most unappreciated sidekick. I mean, I think everyone would want to know who's very unappreciated. I say Scrappy Doo from the Scooby Doo series gets most unappreciated. He saved the series and yet they cast him aside like he was nothing.
