Though an "al" is missing in my countries name, we did the same after the final exams. And it was pretty much fun. We barricaded all doors of the school in the early morning, so that students and teachers couldn´t get in.
And what we shared with (some) Swedish students: We have also borrowed a truck and driver drove us through the city.
But we were a touch less civilised and bespattered passer-bys with water guns. Sigh, being 18 again would be great
