Probably you know the song Yellow submarine from the four guys from Liverpool. But, did you know that in the song you can also hear Slovak language?

And not any, but directly from the mouth of Dezo Hoffmann, who cried out "You can kiss my ass!" and as he himself acknowledged it was his silent reference to the communists in Czechoslovakia, who forced him to emigrate. 

Well, if you want to convince yourself, listen to the Yellow Submarine, and you will definitely make your day with this catchy melody.
