Just a hoax?

[Jorge_Stolfi]

Doctor bullatus, asinus coronatus. That's what you are

I learned that in a famous very very old Italian university - maybe Pisa, Padua, or Bologna -- it is an old tradition that, at the graduation ceremony, as soon as a student receives a Doctoral degree, the audience chants an obscene ditty in dialect,  Dotore, dotore, dotore del ... and the rest would be improper to reproduce here.  With the Distinguished Professors standing there behind the table, impassible.

All the best, --stolfi
