Hi, fellows! I want to tell you a funny prank we played on guys from the next room when I studied in the University and lived in a campus.
The door of rooms opened inside. So, early in the morning we sealed the next room doorway up by several layers of paper. Thus, when a person opens the door, he sees that the way is "immured". Well, paper is not difficult barrier to overcome, so, the victim pushed on it by the whole weight and the papers tore off. But the funniest thing happened the next day! We repeated sealing the doorway up. But that day the victim got another surprise. Again he leaned by all his body weight to tear off the paper, but outside a big basin with water was waiting for him. So mechanically he got into it! Ha-ha!
