Here's an example that I shared in this Mudcat thread:
African American Secular Folk Songs


OLD BILL THE ROLLING PIN

Bessie Jones, Bess Lomax Hawes,"Step It Down" {University of Georgia Press, 1972, p. 208}

Now, Old Bill the Rolling Pin this morning.
Now, Old Bill the Rolling Pin this morning.
Now, Old Bill the Rolling Pin,
He's up the road and back again.
Big eyes and double chin this morning.

I geed to the mule but the mule wouldn't gee this morning.
I geed to the mule but the mule wouldn't gee this morning.
I geed to the mule but the mule wouldn't gee.
I knocked him side the head with thes singletree this morning.

Now Old Bill, etc.

I hawed the mule but the mule wouldn't haw this morning.
I hawed the mule but the mule wouldn't haw this morning.
I hawed the mule but the mule wouldn't haw,
He wouldn't do nothing but the pssum-la this morning.

Now Old Bill, etc.

Mister Frog went swimming down the lake this morning.
Mister Frog went swimming down the lake this morning.
Mister Frog went swimming down the lake.
But he got swallowed by a big black snake this morning.

Now Old Bill, etc.

[sung to the chorus melody]
Mrs. Duck went swimming down the lake this morning.
Mrs. Duck went swimming down the lake this morning.
Mrs. Duck went swimming down the lake.
But she got struck by a big black snake.
Poor thing, her neck got breaked this morning.

Note from book:
"When the mule wouldn't do nothing but the possum-la, that means he'd back around and cut up and like that-like he was dancing...*

Mrs Jones say that Old Bill was a "patterroller" and that people made this song up to make fun of him. During slavery, when Negroes were not allowed to leave their home plantation without a pass, "patterollers" were armed guards, hired to patrol the roads at night, enforcing the pass system. This particular 'patteroller' had "big eyes and a double chin", apparently reminding the singers of Mister Frog {the same one who went a-courting and who got "struck by a big black snake"}. The mule,who dances instead of working,is not as extraneous as he may seem either."
