I remember seeing a theatre production of Amadeus a few years and being surprised (not really unpleasantly) by the scatological jokes. Now I find out it was historically accurate!
I didn't know Mozart composed a ditty about...er...rimming...the more you know!
(These days "Leck mich" is still pretty commonly used in German, to mean "eff you").
Thanks for the article, I am now way too informed about this topic!
