Recipe for a good joke

One contest can get over 4,000 captions. Across 385 contests, that adds up to more than 2.3 million. And while people don’t always agree on what’s funny, the same ingredients keep showing up.

Funny = Brevity + Surprise + Truth

Captions get sorted into “funny,” “somewhat funny,” and “not funny.” Most land somewhere in the middle. “Funny” is rare. The crowd’s a tough judge—and getting a laugh takes real skill.

Out of all the votes, 72% were voted unfunny

8% were ‘funny’ votes

20% were ‘somewhat funny’ votes

Two million captions later, and here’s the punchline: most barely get a laugh. The majority hover just above “not funny,” with only a tiny handful hitting that sweet spot of genuinely funny. The curve drops off fast—like a joke that doesn’t land. Turns out, making people laugh is hard. Even in a contest built for humor, the average caption earns more sighs than smiles.

When we looked at caption structure, punctuation told a quiet story. Captions ending in question marks tended to score lower than those that ended with a period, or nothing at all. The best jokes, it turns out, don’t ask. They declare.

The longer the caption, the lower the laughs—brevity may be comedy's best friend

Shorter captions tended to score higher on funniness, with the sweet spot around 50 characters. Being brief helps—but it doesn’t always mean it’s funny.

To get a clearer picture of the humor landscape, we used a clustering algorithm to group captions by style.

With UMAP and sentence embeddings, we mapped every caption into a 2D humor space—each point is a caption, and each color represents a different flavor of funny.
