Students make a circle. Each one has a small sheet of paper and a pen. Each student has to write one question on the sheet of paper. Questions can be various, on whatever topics they want. Then students give their sheet of paper to the person on their left side. Then this person turns the sheet of paper and writes the answer of his question without looking at the real question written there. The funny thing is that a question written from the person next to you can have a really hilarious answer without any relation to it.
