Leck mir den Arsch fein recht schön sauber

"Leck mir den Arsch fein recht schön sauber" ("Lick my arse right well and clean") is a canon for three voices in B-flat major, K. 233/382d/Anh.A 39. The music was long thought to have been composed by Wolfgang Amadeus Mozart during 1782 in Vienna, but now thought to be the work of Wenzel Trnka.
