When people talk about AI today, two reactions are common:

- excitement
- fatigue from hearing about it everywhere

But there is one well‑known weakness of generative models that everyone recognizes:

**hallucinations.**

Large language models can produce answers that sound perfectly plausible — even when they are completely wrong.

Yesterday I realized something funny.

Human LLMs have existed for decades.

I recently started watching *Cheers* again, the classic sitcom set in a Boston bar. And suddenly it hit me.

One of the regulars — **Cliff Clavin**, the postal worker — behaves exactly like a hallucinating chatbot.

Cliff Clavin:

- can answer *any* question asked
- the answer sounds authoritative and detailed
- fact‑checking usually makes it collapse quickly
- he is absolutely confident while explaining it
- and the explanation tends to be… very long

In other words, Cliff behaves like an **LLM running at high temperature**.

And of course, he never says:

> "I don't know."

Once you see it, it is hard to unsee.

Every workplace probably has at least one human LLM.
