Driving in the car with Iguana (age 9):
Iguana: So....what can we listen to? Do you have anything that's sfirafied?
Iguana: Yeah, sfirafied. You know. What's it called when you have singing but no music?
Me: You mean a capella?
Me: Sfirafied...did you make up that word?
Iguana: (laughing) Yeah!
Me: Good one.
