Lisa Vicek shared this rhyme her grandmother taught her. It's supposed to be said in a heavy Brooklyn (New York) accent...

(See song notes for pronunciation.)

Notes

Lisa Vicek wrote, "This was done in an accent…

Thorty poiple boids
Sitting on de koibs
Choipin and a boipin
And eatin' doity woims
Along came a skoit
Called Goit
And boy was she pertoibed."

Here's a version that can be found in the comments on Duluth News Tribune....

Spoken in a heavy Brooklyn accent.

Thirty, dirty, purple birds
Sitting on the street curb
Eating earth worms and
Chirping and burping.
Along came Gerty
The girl with the curls
And her boyfriend, Herbie
Who works in the shirt factory in Jersey
They saw the thirty, dirty, purple birds
Sitting on the street curb
Eating earth worms and
Chirping and burping, and
They was perturbed!

Here's a version from Yahoo Answers:

Toidy poity poiple boids
Was poiched onna coib,
On Moitle, near toidy-toid n' toid,
A-choipin' an' a-boipin,
Eatin' boidseed n' oit'woims,
N' along comes Doity Boity,
N' his goilfriend Goity
(Who works in da Vinegar Works in Joisy),
N' was DEY poitoib'd!

Here's a version from "A Way with Words Podcast":

"Toidy poipel blackbirds
Sittin' on a coibstone
Choipin' and boipin'
And eatin' doity oithworms."

Version by the Red Hot Chili Peppers on their album from 1985:

Thirty dirty birds
Sitting on a curb,
Chirping and burping
And eating dirty earthworms.
Along comes Herbie
From thirty third and third,
Saw the thirty dirty birds
Sitting on the curb
Chirping and burping
And eating dirty earthworms,
Oye, was he disturbed.

There's also a 1944 song called Toity Doity Boids.

Foity Poiple Boids

Foity poiple boids sittin on the coib
Along comes Hoiman and his goil
And Hoiman's goil was so petoibed
To see the foity poiple boids
Sittin on the coib.

"Dez a woim in dah doit!"
"Don't woeey," Sez Hoiman,
"Dah woim won't hoit!"

Elaine Corral sent this version:

30 purple birds
sitting on a curb
chirping and burpin
and eating dirty worms.
along came a man
from 33rd and third
and saw those 30 purple birds
sittin on a curb,
chirping and burping
and eating dirty worms
and he was so perturbed.

There were toity poiple boids sitting on a fence at toity toid and toid avenue foist.

Along came Hoiman going to the Vinegoi woiks, and Hoiman saw the toity poiple boids sitting on a fence at toity toid and toid avenue foist.

And Hoiman was poitoibed.

In Standard English it's:

There were thirty purple birds sitting on a fence at thirty third and third avenue first.

Along came Herman going to the vinegar works, and Herman saw the thirty purple birds Sitting on a fence at thirty third and third avenue first.

And Herman was perturbed.

Along comes Boit (Bert) and his skoit, Goit
Who woiks in a shoit fact'ry over in Joisy City
An' they saw them thoity poiple boidies sittin' on the coib
Choipin' an' boipin' an' eaten' doity woims

An Boit says to Goit, 'Ain't that petoibin?'

It's the longest version I've seen."

Boy was they moitified!"
