A well-placed joke can make a difficult subject feel easier to approach. It can also distract from the explanation. The useful question is whether the humor helps the reader follow the idea.
Research on humor in advertising offers a starting point. Those findings concern ads and audience responses, so they cannot tell us that a joke will improve learning in every technical article.
Attention is one result, understanding is another
In a meta-analysis of humor in advertising, Martin Eisend combined 369 correlations from prior research. Humor was associated with greater attention and more positive feelings toward ads. The analysis also found lower perceived source credibility on average. These are effects in advertising studies, not a direct test of how well a reader understands a technical explanation.
Attention gives an explanation a chance to be seen. It does not establish that readers understood it, trusted its source or could use the idea afterward.

What sharing research actually studied
Tellis and colleagues examined online video advertising in two independent field studies, with a third study testing their predictions on a separate sample. Amusement and other positive emotions were associated with sharing. Their analysis covered video ads across social platforms, so its result should not be treated as a forecast for a written tutorial or a particular audience.
A share can have many motives. The study does not show that every joke earns a share, or that the person sharing learned the underlying topic.
Make the joke serve the explanation
One practical approach is to introduce an analogy with a light touch, then explain exactly where it stops working. For example, a queue may be compared with people waiting at a counter. The useful part is the order of requests. The real system may also retry, prioritize or process work in parallel, so the comparison needs those limits.
This is an editorial technique, not a measured learning effect from the advertising studies. A reader should be able to distinguish the example from the actual mechanism.

Keep the evidence easy to find
-
Put the factual claim and its source close together.
-
Use humor around the example rather than changing the numbers or the conclusion.
-
Read the passage without the joke. The explanation should still be clear and accurate.
When the subject involves real harm, a casual joke can land badly. Consider who is affected and what the reader needs from the material.
Humor can make an opening more inviting. Its value in an explanation depends on whether it leaves the reader with a clearer, accurate account of the subject.
