Most science is not hilarious. Science is slow, it involves repeating the same action tens or hundreds or thousands of times, and it often investigates deeply unfunny subjects such as cancer or polymer synthesis. That's why the rule of the One Funny Thing is such a relief.
The rule goes like this: If you read a paper all the way through, top to bottom, you have a good chance of finding something funny. It's usually hiding in the Methods section. Now, I can't vouch for the aforementioned cancer and materials science studies, and I admit the humor in most astronomy papers eludes me. But I always feel reassured to find something silly tucked away in an otherwise serious, peer-reviewed paper.
What follows is a collection of funny things. Some of them are from studies I've written about on this blog, in which case you can follow the link to get to the original story. Others are studies I've read for work. Going forward, when I cover a story that follows the rule, I'll label it with the "One Funny Thing" tag. Clicking that tag will take you back to this page, where I'll add the new tidbit at the top of the list.
