A little background: We're using La Clase Divertida for Spanish right now. It's DVD-based, and the instructor teaches the kids the alphabet by using a chant: "A, araña, b, bandera..." and the kids do hand motions to match each of the sample words.
Goose: "Mom, what does 'araña' mean?"
Goose: "Oh. I thought it meant 'evildoer' because of the way they put their hands. (Holds her hand with the fingers spread out and facing down, like spider legs.)
SOM: (laughing) Evildoer. You mean like the villains on TV? (I imagine any garden-variety villain on Scooby Doo.)
Goose: (laughing) Yeah!
