Considering the Residence Americka Park in Prague?

Beer crazy guards by sabsi
Sitting on a wall at the castle at night overlooking Prague when the guards (who aren't allowed to talk normally) started whispering 'Bsssst...PIVO!' so that we'd give them a bit of our beer. Really funny! Another funny situation was when my friend realized that he'd bought alcohol free beer because the label looked good HAHA ;-)
