Add "Breakfast of Champions" entry documenting the __phello__.spam, __phello__.ham, __phello__.ham.eggs frozen modules references Monty Python's SPAM sketch.
Add "Unreachable State" entry documenting some funny error messages in CPython's Py_UNREACHABLE() macro, including the `RANDALL_WAS_HERE` build flag referencing xkcd author Randall Munroe.

There was a problem hiding this comment.
Perhaps python/cpython#119535 is a better page to be linked, because there were three pull requests relevant here (add pythonπ, change it to πthon, remove it in 3.15).
Besides, it might be worth noting that only the original CPython has this easter egg.
Specifically, Python 3.14 installed via uv python install 3.14 and venv created by uv venv do not support it. They don't use Lib/venv/__init__.py, where the easter egg is implemented.
astral-sh/uv#16240
Typing 𝜋thon (U+1D70B, a valid Unicode identifier) inside a Python 3.14 virtual environment launches Python. Only works with CPython's own venv e.g., venvs created by uv does not support it.

Document three more Python Easter eggs:
#16 — Breakfast of Champions
The phello package is a frozen CPython module used for testing. Importing
phello.spam and calling .main() prints "Hello World!" — a nod to Monty
Python's SPAM sketch.
#17 — Unreachable State
A macro in CPython's C source that marks code paths that should never execute.
The RANDALL_WAS_HERE build flag reveals humorous error messages written by
(and referencing) xkcd author Randall Munroe, alongside an equally self-aware
Py_DEBUG message.
#18 — 𝜋thon
In Python 3.14 virtual environments, typing 𝜋thon (U+1D70B — a valid Unicode
identifier) launches Python. A clever play on the 3.14 (pi) version number.
