OK I listened to that song like 5 times while writing this. I hope to never hear it again.
Something like this...
At the science institute an experiment is being conducted
the effect of film is being tested on humans
how old movies of questionable quality influence consciousness
Stepa is a good guy who needs money
he signed up for the experiments ignoring risk and fear
but he didn't know that the experiments are conducted by an evil genius Prof. Zamyshljavkin (from the word that means to concoct)
Stepa is now trapped watching movies and if it wasn't for his friends he'd be doomed
infiltrators -- dog and a penguin -- save his mind and watch the movies with him
Fidel (penguin) -- Ketchup (dog) -- the best achievements of national defense (?!)
When the friends are all together, they do not fear the villain. They keep commenting (on the movie) so it's more fun. In defiance of scientific theories they laugh watching Project Popcorn.
