All foods are either "tasty" or "sweet". Sweet foods (which include such divergent selections as fried rice or macaroni and cheese) are not be consumed at night because they'll keep him awake. He did explain once that macaroni and cheese had too much sugar in it to be eaten before bedtime. Tasty foods, on the other hand, are quite safe before bedtime and, in fact, help him to go to sleep. These include things like salt and pepper potato chips and a wide variety of other foods that I can't recall at the moment.
Use Hyperbole wherever possible as in the following example:
"She's the naughtiest girl in the WORLD!"
"It's a really good thing I didn't drop my OTHER chopstick on the floor too!" (Overheard at a Chinese restaurant last night)
