Baa baa black sheep
Paddy waddy wool.

The story:

My husband sang the first line "Baa baa black sheep" and I sang the second "paddy waddy wool" and he stopped and stared at me. Then he said "are you serious?" and started laughing hysterically. I insisted that's the way my mother taught me the song. He asked my sister what the words were and she sang it the same exact way!!! He will never let us live it down.
