lol, my DS6 did things like this a lot last year. He did little things to amuse himself. Spelling it backwards, scrambling the letters, writing some big and some small, doubling the letters, etc. Of course that is better than when he was 3yo in prek (and some at 4yo) writing "my name is poop" on the paper. He thought that was quite amusing. The teachers did not agree. They do lots of things to make their work more interesting. He even went through a little stage of intentionally mispelling words and trying to write like the other kids do.
