W: Welcome to our program. This week, we would like to talk about what science and comedy have in common. Welcome, Adam.
M: Thank you.
W: Imagine that a physicist and a biologist walk into a bar. There’s a reason science and comedy don’t usually mingle. But to biologist and comedian Adam Ruben, the two are related in more ways than one.[1] Ruben uses insights from his Ph. P. training and years of working in a lab to write Experimental Error, a humor column for Science Careers. He will share interesting things with us. So Adam, what do science
and comedy have in common?
M: Well, [2] I think something that they have in common that people forget is that they’re both serious pursuits. I think a common misperception of comedy is that it’s not something serious; it’s not a real field. [3] And I really wanted to teach a class on stand-up comedy—the history of stand-up comedy and its impact on society. And I pitched this class, and I was eventually told by the committee that they would never accept this class because it just wasn’t about a serious topic. And I think it’s a shame to dismiss comedy. It’s as serious as any other forms of self-expression or social commentary. But science sort of already gets that, that little benefit of everyone hearing science and they assume it’s serious.
W: [4-1] We know that you’re a funny guy. But are you funny in the lab or do you keep your scientist side separated from your comedian side?
M: [4-2] I actually do keep the two separated, and that’s mainly because I’m paranoid. [5] If you try to be funny in the lab too much, people will use it as the ready excuse for anything that goes wrong in the lab: "Oh, well, it’s because he’s focusing too much on trying to be funny. " I had an experience in the graduate school where my advisor found out that I did stand-up on the side, and all of a sudden it became the reason why my experiments weren’t working. He said, "Oh, it’s because your mind is not on science, it’s on stand-up comedy. "
