If you say in our house "Shut up the drawer without the drawer", World War III breaks out. I read about this in a novel once that two kids would say it to avoid their mother telling them off for saying "shut up"... quite funny I thought but my kids get in such a fankle over it ("it doesn't make sense!"). So from time to time we throw it in there...
Any similar phrases in your house?
(Light-hearted if that's not obvious!)
