What do you know about jokes??? I remember when I was still in school, on the first of April in the female teacher's toilet hanged a toilet paper, which at home, his own hand impregnated with a tincture of peanut pepper. The paper was pink and nobody noticed the subwooch... In general, our class had two lessons disrupted, because of the fact. The teacher burned. There were lessons in other classes too. Fortunately, nobody knew who exactly did it.
