Let me correct you on a few things. Aristotle was not Belgian. The central message of Buddhism is not "Every Man for Himself". And the London Underground is not a political movement. Those are all mistakes Otto. I looked 'em up.

Our reading
An editorial interpretation.
The speaker is setting the record straight, listing three absurd errors: Aristotle's nationality, Buddhism's supposed creed, and the Underground as a political movement. Having checked them, the speaker presents the corrections with brisk confidence, which makes the mistaken claims sound even sillier. The humour lies in the deadpan, pedantic tone.
