Have you ever watched a film called "Fight Club"? It tells a story of an ordinary man who had been sufferring from insomnia until he found an imaginary friend. AS a result they organized "Fight Club" - a rather specific place where all men could come and fight with each other. Of course, fighting with your best friend may sound a bit strange, but guess what? It seems like even animals enjoy being mates for a day and enemies for an hour! Watch these hilarious couple practising their kickboxing skills and prove!
