A friend of mine had to answer what was the difference between analytical cubism and synthetic cubism. His reply: "Analytical cubism reduced everything to basic shapes: people looked like cubes, trees looked like cubes, and even cubes looked like cubes (how mean!). Synthetic cubism was not so extreme, so people still looked like people, trees still looked like trees, and cubes, well, those still looked like cubes." He got full mark.
I never did anything of the sort, but I would always doodle on the side of the tests and teachers would sometimes doodle back. Once there was a question about Machiavelli's 'The Prince', and the title was on a line break, so I wrote 'Little' on the space ('The Little Prince'). When I got the test back, the teacher had written: 'Nope, this is the big one!'
