On Facebook someone suggested instead of Haiku, in March we do Limericks!

For those who aren't familiar it is generally fun:
They are five lines long.
Lines 1, 2, and 5 rhyme with one another.
Lines 3 and 4 rhyme with each other.
They have a distinctive rhythm:
They are often funny

The rhythm is “anapestic,” an easy way to say it is:
da DUM da da DUM da da DUM
da DUM da da DUM da da DUM
da DUM da da DUM
da DUM da da DUM
da DUM da da DUM da da DUM

My initial contribution:

My brain does not limericks do
As nicely as it does haiku
I'll try hard to play
But won't promise each day
So the rest will be up to all you!
