The Rigatoni Song de Malvina Reynolds

I know a little girl,
She likes to dance and sing,
She likes to make up funny words,
And that's another thing;
She calls this thing my rigatar,
She likes to hear it sound,
So while I play a rigatoon,
We'll rig-a-jig-jig a round.

Oh rigatar, rigatoon, rigabeat.
Rigatoni's good to eat.
