Ever feel like you've been to so many weddings that you've seen it all? Bet you've never seen this happen. Before saying their "I do's", a couple in Russia received a major wedding day surprise when a building in Kostroma collapsed right behind them. It was all captured by the wedding videographer and the resulting footage is amusing to say the least (importantly, no one was hurt). As the saying goes: something borrowed, something blue, something...crumbly?
