Today’s XKCD comic had the following ALT text:

Wikipedia trivia: if you take any article, click on the first link in the article text not in parentheses or italics, and then repeat, you will eventually end up at "Philosophy".

I felt compelled to put this to the test with a single example.  Would “Toothpick” lead me to Philosophy?  If so, how many clicks would it take?  Here is the result:

  1. Toothpick
  2. Wood
  3. Plants
  4. Life
  5. Physical body
  6. Physics
  7. Natural science
  8. Science
  9. Knowledge
  10. Fact
  11. Latin
  12. Italic languages
  13. Indo-European languages
  14. Language family
  15. Language
  16. Communication
  17. Meaning (philosophy of language)
  18. Aristotle
  19. Greek philosopher
  20. Greeks
  21. Nation
  22. Sovereign State
  23. State (polity)
  24. Social sciences
  25. Umbrella Term
  26. Subset
  27. Mathematics
  28. Quantity
  29. Property (philosophy)
  30. Modern Philosophy
  31. Philosophy

That’s a pretty circuitous route, but sure enough, Wikipedia connected Toothpick to Philosophy just as XKCD said it would.
