While sitting on the couch, shortly after the possibility of going gluten free came up:
Me: Hey, can I have a back rub. I can't eat gluten, you know.
Luke (after a moment's hesitation): Sure, but I'm tired, so it will be barley a back rub.
Me: Wheat do you mean? Come on. Please?
Luke: Fine. I guess I am a gluten for punishment.
