Loser's Guide to Life
According to the story on RIA Novosti, some Chinese toys were detained at customs in Novosibirsk because upon inspection they were discovered to be capable of singing songs by Russian composers for which neither the manufacturer nor the importer had secured permission.
One of the songs at issue is “Antoshka, Antoshka, Let's Go Dig Potatoes”, by Vladimir Shainsky.
You can see a YouTube of the cartoon and song here.
Copyright is no joking matter, of course, but I'm just thinking about the customs officers winding the toys up (or whatever), hearing the familiar melodies, and then gradually realizing: this could be a very grave problem.
