Early Limericks

I was looking through some of my writing and I found these Limericks that I wrote. These are basically the first ones I've ever written, and I haven't written many more sense. I ought to try my hand at some more.
Hey, why don't you try writing some? The pattern is an aabba rhyme scheme where the third and fourth lines are generally shorter.

There was an old man yesterday
who was sitting on a log at the bay.
The log rolled
and his pants got soild
so he won't be there next monday.

There was a mad scientist
talking to an insane priest
they each shouted
'till both pouted.
Neither came to the logicians feast.

A lass without her own house
was taunted by a little mouse
That's quite rude
and very crude
to be so bold, a thing high as a louse.

Lost in a maze of corn
a woman was feeling worn
so she stopped
and there popped
and thus a puzzled child was born.

In a good mans dizzy skull
the world seemed to be made of wool.
His head on the brink,
he said, "I can't think!"
So a sponge gave him a headful.

Looking for a meadow lark
a dog suddenly began to bark.
It had found
on the ground
a sneaky smurf in the dark.

There was a man wearing blue
who asked if anyone knew
where we went
to get so bent
and he got his answer from you.

Sitting in a five foot arm chair
sat a man who never would dare.
"It's safe" he said,
so at home he staid.
'till his seat fell hard on his hair.

There's a yellow chimpanzee.
It never was much bother to me,
But Bill
had his fill.
Bill's such a stingy bannanna tree.

There was a man in a red cap
who aimed a bear to trap
so he got a dart
thinking himself smart
but all he got was a bit of tree sap.

Some Limericks I tried to write
and found that it took some might
for though I could
they weren't as good
as some of us would have liked.

You may have noticed a rhym
on some occasion, or at some time
that didn't quit fit,
and gave you a fit,
caus technicaly it's "identity" to say "teatime."

In the greatest MMORPG
that I ever in my life did see
a haiku dungion
deserves acclaimation
and yet the limerick one escaped me.

On too common an occasion
the rock escapes abbrasion
by sitting
not fitting
as the brains of a legion.
