One Russian farmer decided to equip his cow barn with... LED TVs.
He has got from somewhere the information that cows get more happy and productive if they watch the movies with the juicy green fields. So he got a non-stop loop of world's recognized green Swiss Alpine fields and got the most slim lcd tvs on market in Russia and then called the team of workers to install that all.
Now they go into statistics to measure the outcomes. They compare the results from two groups of cows, one is watching tv another is deprived of this humanity most spread entertainment thing.
