The email address from which it came ( firstname.lastname@example.org ) is probably not genuine, so I wonder who the author could be (the final note “Translated, from the Spanish, by H.A.H” is of course suggestive, but one would then like to see the original Spanish…)
For those readers who understand spoken French (or simply appreciate the musicality of the language) and are interested in the history of mathematics, I warmly recommend listening to the recording of a recent programme of Radio France Internationale entitled “Pourquoi Bourbaki ?” In addition to the dialogue of Sophie Joubert with Michèle Audin and Antoine Chambert-Loir, one can hear some extracts of older émissions with L. Schwartz, A. Weil, H. Cartan, J. Dieudonné, for instance.

The Swiss stereotypes do not usually suggest a great sense of humor. But since I’ve been in Zürich, I’ve noticed a certain style of quiet understated humor, in particular in advertising.
Here’s one ad for the most famous vegetarian restaurant in Zürich (probably the best in the world):
Here’s an ad for the Zürich public transportation system; the left-hand man is a right-wing politician, and the right-hand one a socialist (I had to look this up; I’m not really up to date on local politics), and the ad says that fortunately there is a tram stop on average every 300 meters…
Here’s a recent ad to warn against swimming in the wrong places in the river, despite the absence of sharks (Hai means shark in German):
As pointed out by Philippe, this abstruse goose cartoon shows that analytic number theory is now part of the Zeitgeist.
