I happened to have a John Butler CD on in the car driving back from the river this afternoon. It didn't need much prompting (though some, fair's fair) from me to get Ella to sing the Treat Yo Mama With Respect song. I got her to sing it at least 5 times while we were walking through the supermarket and cackled victoriously for about half an hour after.
Such fun when you know they don't know what they are singing too. Though eventually I did explain to her that it means you have to be nice to your mama and to her credit, she liked the song even more then.
