Made Me Laugh

Conversation at the dinner table tonight:

Noah: "Napkins are for going in your lap." (unfolds napkin and begins to place in his lap.)

Me: "Well, yes, that is good etiquitte if you are eating in a restaurant."

Noah: (looking perplexed, removes napkin from his lap and places it back on the table) "Nevermind, I don't want it in my etiquette."

Where do they come up with this stuff?? All I know is they keep me laughing.
