Songwriter, composer, and comedian Ivan Mládek has been one of the heroes of my childhood and I still enjoy his work (as I told him a month ago during a Christmas party; he was also a classmate of President Klaus). He has written hundreds of funny songs and I have memorized most of them. However, "Koukejte vycouvat" (Back Your Car Out Of Here) above has been one of my favorites. For amateurs, I find the LEGO videoclip by Mr Big Stalk and Mr Little Stalk (Košťál and Košťálek) rather impressive.
Another huge hit was "Jožin z bažin" (Josh from the Swamps), the Lumo #1 hit of 1978 and 1979, that I also offer you in a LEGO version; see also a videoclip with Ivo Pešák's Parkinson with Polish subtitles. Right now, thirty years after it was written (for one bottle of alcoholic beverage), it is becoming a successful hit in neighboring Poland and the YouTube video in the previous sentence has over 1 million of Polish visits. Another million has visited copies of the same video. And it is number one on Polish radios; see Polish TV.
I don't fully understand the dynamics behind this development but the Poles must find not only Ivo Pešák's dancing but also the Czech language very funny, maybe even more funny than the Polish language is for the Czechs.
