This cartoon makes a wonderful point about mad scientists:
Naturally I thought it could be improved with some art from the first Max Fleischer Superman cartoon, generally referred to as The Mad Scientist:
Bystander: Why did you build a death ray?
Madman: To take over the world!
Bystander: No, I mean, what mad hypothesis are you testing? Are you just making mad observations?
Madman: Look, I’m just trying to take over the world, that’s all.
Bystander: You’re at least going to leave some of the world as a mad control group, right?
