June 1st is a holiday in Russia with an odd name of "International Day of Children Defense." The day is typically associated with the last day of school and celebrated with a "Lineika" (lit.: line-up in a row) when the entire school (in Russia elementary, middle and high schools are often in the same building) is lined up in the schoolyard for some parade-like gathering. I had to suffer through these for 10 years in a row always wishing for something out-of-ordinary or funny to happen. Something like in this clip, I guess :)
