A student was lucky to find a decent accommodation with a cheap rent. His colleagues came to visit him and he was showing them the house.
"This is the kitchen. This is the bedroom. And this one is the living room ... " "And what are this hammer and this pot that are hanging on the wall for? What are you going to do with them?" one of his colleagues asked. "This is a talking clock." "I have never seen a clock like that. Can you show me how it works?" "Sure. Look," the student said. He took the hammer and struck at the pot with all his strength. Then a voice was heard from the other side, "What you are doing? Are you crazy? It is half past one in the night, you idiot!"
