Little boy, how old are you?

Little boy, how old are you? (3x)
I'm only three years old.
Who told you so?
My mama told me says.
(Chorus)
What your mama say?
My mama tell me, too.
(Chorus)
How'd you know it, keep up with it so long?
`Cause I never did forget it my age was.
I'm only three years old, my mama told me
Only three years old, my papa told me
Only three years old.
