In first period English class, we were further in the material than the other classes. So, the teacher told us to push our desks in a big circle, and he passed out lined paper, on which we had to write: "The last thing I remember hearing was..." and then we completed the sentence and passed it on to the next person in the circle, and then they would write something while being timed. When time was up, we'd pass it on to the next person.
The Touhou part here is that after a while, I didn't know what to write, so I started writing Touhou references, such as about Koishi, Mima (tempura-butt joke (Wind Priestess Quest)), Buta-Otome, of course, Cirno.
