I was just cleaning out my computer and found this little Limerick:
Greg's Unifnished Drupal Limerick
There once was a CMS named Drupal
With code, the developers were frugal
It's only 2megs
Taxonomy means tags
I like to play the bugle
I think I wrote this 2 years ago.
As you can see, the last line is pretty weak. I think the basic flaw is that I ended the first line with Drupal and then had to try to rhyme something close to it which is kind of hard.
