Limerick competition

With a limerick, try, if you can,
To ensure the appropriate scan.
If you write it like this,
I'm afraid you will miss
The wonderful prize I'm giving for the best Limerick.

I'm puzzled at the number or people who can't write limericks that scan properly (not my erudite readers, naturally), so I'm offering a small mystery prize for the best limerick on the subject of ...writing limericks. Winner to be chosen by the readers.

No rules, no fee. I'm just trying to make sure at least some of you waste some time, too. It'll make me feel better.
