Scribbling As Memory Aid

I often doodle while listening to lectures. 

My wife has taken this to mean that I am not paying attention. But now I am vindicated:

Researchers in the United Kingdom found that test subjects who doodled while listening to a recorded message had a 29 percent better recall of the message's details than those who didn't doodle.

Now we need a follow-up study, on people who write verse while listening to lectures.

If doodling's
a good thing,
can verse
be worse?
