When I was 13 or something, with a friend we were bored during the afternoon, his parents weren't there, and we decided to make a giant water bomb, with a sport bag, and there was like 10 liters of water in it, and we added little cars, marbles, and chinese chopsticks for good measure. Then my friend threw it out of the window. He lived at the 5th floor of a parisian building... It landed right on a car parked near by, the car "exploded", fucking bent, and we were oh shit oh fuck and we closed the windows fast and ran in his room. Then we started playing some shit, and then his father came home. And he was fucking dark mad, and he said, "floriant, what is this..." while holding a marble between his fingers... And floriant my firend said "Well, it's a marble?" and then his father said "floriant, there's a guy downstairs, crying near his completely destroyed car..." and floriant said "I swear dad I know nothing!"and his father said to me "you... You take your stuffs, and you get the fuck out..." Later... Our parents decided it was better we never meet ever again... LOL
