May a cock-sparrow
Write to a barrow?
I hope you'll excuse
My infantine muse
-------Lewis Carroll

Any others? The sillier the better!

Edit:
I am very sorry if this thread is inappropriate for the time. It came out of a desire for something easy to understand and simple (even childish).

Oh Mamie minded mama
Till one day in Singapore
A sailorman from Turkestan
Came knocking at the door.

   -- Walt Kelly

Can anyone lend me
Two eighty-pound rats?
I want to rid my house of cats.
-Shel Silverstein

A wonderous bird is the pelican
His beak holds more than his belly can

and

The turtle lives twixt plated decks,
which almost entirely hide its sex
I think it clever of the turtle
In such a fix to be so fertile.

Limerick
There was an old man from Nantucket
Who kept all his dough in a bucket.
His daughter, named Nan,
ran away with a man.
And as for his bucket
Nan tucket!

thanks wow, do you know more about Nan, who ran off with that man? there are about 5 limricks in the series.

i forgot the author of this, one of my favorites, but Kieva was kind enough to look it up, Anthony Euwer

As a beauty I am not a star,
there are others more handsome, by far,
but my face, i do not mind it,
for i am behind it..
it the people in front that i jar!

and edward lear's
there was an old man with a beard,
who said "It is just as i feared,
two owls, a hen
three larks and a wren,
have all made their nests in my beard!"

A wonderous bird is the pelican
His beak holds more than his belly can
He can keep in his beak
Enough food for a week.
I'll be darned if I know how the hellican.

And further Nash trash:
The ant has made himself illustrious
Through constant industry industrious.
So what? Would you be calm and placid
If you were full of formic acid?

Paul Gilbert:
I love you, my lord!"
Was all that she said --
What a dissonant chord,
"I love you, my lord!"
Ah! how I abhorred
That sarcastic maid! --
"I love you? My Lord!"
Was all that she said.

Unknown:
'Tis midnight, and the setting sun
Is slowly rising in the west;
The rapid rivers slowly run,
The frog is on his downey nest.
The pensive goat and sportive cow,
Hilarious, leap from bough to bough.

Oy, perhaps someone knows the beginning and end of this one. I only remember middle part that states...

"I see," said the blind man
to the deaf cop.

Something to do with a robbery or something.

Ladies, maybe you'll remember...the skipping rope songs were generally silly verses (same with elastics songs). Does anyone remember any?

Jumprope song:
"Cinderella,
dressed in yella,
went upstairs to kiss her fella,
made a mistake and kissed a snake;
how many doctors did it take?"

there is a traditional american verse, which has several varients,

One dark morning, in the middle of the night
two dead boys got up to fight.
Back to back, they faced each other,
drew their swords and shot each other,
a deaf policeman heard the noise,
and came to the rescue of the two dead boys
if you don't believe my story, ask the blindman,
he saw it all!

for jump rope, there is always

miss mary mack, mack, mack
all dressed in black, black, black
with silver buttons all down her back, back, back

which i find, i can't remember the rest of.

knocking round my head are lots bits and pieces of many street songs, some of which are american varients of Childs Ballard..
"he played upon a ladle, a ladle, his name was achin drum.."

I'll raise you, Jackie:

Cinderella, dressed in yella,
Went downstairs to meet her fella,
On the way her panties busted,
How many people were disgusted?
1, 2, 3, 4

cited in Ian Turner's "Cinderella dressed in yella", 2nd ed, [Melbourne] 1978. (A wonderful collection of Australian children's play rhymes.)

paulb, if that's a children's rhyme, Australian children must be pretty ribald! I would think it was a drinking ditty.

I'll raise you, Jackie:
Paulb, trust you to know something like that!

Actually, kids are much more ribald than you think. I remember getting kicked off the 7th grade volleyball team for altering a ditty. Of course my alteration wasn't nearly as ribald as the other kids' that turned me in. And what about "I see London, I see France"?

And your alteration, and the original alteration, were ...? (This is a No-Coyness Zone, and I recall you professing that Adventure is your middle name.)

My alteration of "Clementine" was simply to change '49ers to '69ers. Much more innocent than Jack and Karla's ditties which I have since forgotten.....

Ah, memories. In my school too, 7th grade was when we discovered the interplay between wordplay and foreplay. I still remember Ms. Logan, age 13, and her choice of a pithy four-letter verb to examplify the the difference between active and passive sentences.
