The Dangers of Cooked Music

In preparation of an after school activity our music teacher was practicing the piano piece while the van riders were waiting.  One boy came up to me and said "His music reminds me of when my mom cooks." Thinking he meant she played music while cooking.  "Oh, really?" I said.  "Yes. But when you cook music it is poisonous, you could die. You can't eat cooked music."  With his logic I assume you can only eat raw music.
