Wersję po polsku juz znacie... :)
The situation happeded in primary school, when i was five.
One day i came to school with my favourite toy-a hammer. It was made with rubber. It was a quite early, so i sat on the banch in the corridor and i was waiting for my lessons. A while later principal sam me beating myself with hammer in my forehead... She asked me what i was doing. I replied: "I am trying to knock off my head a lot of stupid things because I am really serious student.". From that day Principal laughs when she see me.
