I Miss My Daddy

My 3 year old roommate says while drawing:

"I miss my daddy."
draw draw draw...

"He's in Cal-ah-for-nah."
draw draw draw...

"He broke his yoke."
draw draw draw...

I don't think a little boy has said, "broke his yoke" for at least 50 years. Where did he get that? Hanging out with hillbillies?
