Once I asked one of my students, “Can you name me an animal that flies?” All the students raised their hands and I chose one he told me an elephant is an animal, which flies. I told him that his answer is so stupid and sure, his father told him that answer so I asked him “where does your father work you idiot?’ He told me that his father is a lieutenant. I answered “Oh what a smart boy an elephant can fly but just if it gives it a try.”
