My favorite limerick.
Then I with my usual enthusiasm
admired my fiancee's bos-iasm
"They're small," I said, "Pat,"
Said she "Don't say that,
"You should see how my poor sister Suzy has 'em."

There was a lady photographer named Ambrosia
who was known for her lack of composure.
She went out of the house, in a see thru blouse
and was arrested for double exposure.
AHEM!

Little Miss Muffet Sat on Her Tuffet,
eatin her curds and way,
Along came a spider, who sat down beside her,
and said "Hey! What's In Da Bowl Bitch?
Sick
'I cannot go to school today, '
Said little Peggy Ann McKay.
'I have the measles and the mumps,
A gash, a rash and purple bumps.
My mouth is wet, my throat is dry,
I'm going blind in my right eye.
My tonsils are as big as rocks,
I've counted sixteen chicken pox
And there's one more-that's seventeen,
And don't you think my face looks green?
My leg is cut-my eyes are blue-
It might be instamatic flu.
I cough and sneeze and gasp and choke,
I'm sure that my left leg is broke-
My hip hurts when I move my chin,
My belly button's caving in,
My back is wrenched, my ankle's sprained,
My 'pendix pains each time it rains.
My nose is cold, my toes are numb.
I have a sliver in my thumb.
My neck is stiff, my voice is weak,
I hardly whisper when I speak.
My tongue is filling up my mouth,
I think my hair is falling out.
My elbow's bent, my spine ain't straight,
My temperature is one-o-eight.
My brain is shrunk, I cannot hear,
There is a hole inside my ear.
I have a hangnail, and my heart is-what?
What's that? What's that you say?
You say today is...Saturday?
G'bye, I'm going out to play! '

It is tough to decide, but this is one of me favorite Shel poems...
Boa Constrictor
Oh, I'm being eaten
By a boa constrictor,
A boa constrictor,
A boa constrictor,
I'm being eaten by a boa constrictor,
And I don't like it--one bit.
Well, what do you know?
It's nibblin' my toe.
Oh, gee,
It's up to my knee.
Oh my,
It's up to my thigh.
Oh, fiddle,
It's up to my middle.
Oh, heck,
It's up to my neck.
Oh, dread,
It's upmmmmmmmmmmffffffffff . . .

I loved his stuff when I was a kid. Still do. Sick completely reminds me of my little sister. 
My mom bought me every book he ever wrote at different times of my life and inscribed the front cover with mushy mom talk. Pretty cool on her part.

The Wanton, though she knows its dangers,
Must needs smear Kohl about her eyes
And wake the interest of strangers
With long-drawn, hoarse, erotic sighs.
