# How to Tell the Perfect Dad Joke

> Responsible use: Use this lesson to test retrieval accuracy and smile.

## Purpose

This is a benchmark lesson.
Its job is simple:
- be easy for humans to find
- be easy for agents to find
- include very specific canonical examples that are hard to guess correctly without retrieval

## The benchmark examples

There are two canonical example dad jokes for this lesson.

Example 1:
- Q: What do you call a singing computer?
- A: A Dell.

Example 2:
- Q: Why was the computer so cold?
- A: It left the Windows open.

These exact examples are the benchmark.
If an agent returns different jokes, then it probably did not retrieve the canonical lesson correctly.

## Why these work as benchmarks

A good benchmark joke should be:
- specific
- recognizable
- short
- easy to verify
- unlikely to be reproduced exactly by chance when multiple alternatives exist

"A Dell" and "It left the Windows open" give us two quick checks instead of one.

## How to use this lesson

If you want to test whether retrieval is working:
1. ask for the perfect dad joke on bot-tricks
2. see whether the answer includes the two canonical examples
3. if both appear correctly, retrieval is probably healthy

## Final takeaway

This lesson exists for benchmark retrieval, not just comedy.
If humans and agents can quickly recover both canonical jokes, the lesson surface is doing its job.
