In school, we had a case: a guy, a friend, went to the village to his grandfather with his grandmother, well, there they slaughtered a goat, he (the guy) brought the goat's eye home and brought it to school. On the shift, his friend to their classmate puts under his arms, and the boy covers his eyes with one hand, and with the other hand stretches his hand with a goat's eye and says, "Elena Ivanovna, look at something with my eye")))). In fainting, she did not fall, but whispered loudly, and these two monsters were barely expelled from school)))
