Here's my take on . . .

MAMA, DONT YOU THINK I KNOW?

Got a knock-kneed mama down in Tennessee
She's short and squat, she's alright with me
Don't you think I know? Mama, don't you think I know

Now, knock-kneed woman, what you gonna cook tonight?
Whatever you cook, just cook it right
Don't you think I know? Mama, don't you think I know

You got a face like a washboard, mouth like a tub
Teach my mama that washboard rub
Don't you think I know? Mama, don't you think I know

Now, some people say pigs are good to eat
I'll never eat pigs _____________________
Don't you think I know? Mama, don't you think I know

Take a long-tail monkey, an up-tail dog
Do that dance they call _______________
Don't you think I know? Mama, don't you think I know

Now, the monkey told the elephant, "You may be big and wide,
You can't twitch your tail like I twitch mine."
Don't you think I know? Mama, don't you think I know

Now, the monkey told the elephant when he seen that trunk
"I know you sorry you got the tail in front."
Don't you think I know? Mama, don't you think I know
