Hey, we learned a new word today. It is really a word. For real. Want to know what it is? U.P. (insert laughter) Really, U.P. It is a word, for real. Why aren't you laughing? Can you believe that? U.P. Get it? Up is U.P. Mrs. Bell said so. It is a word. A "U' and a "P". MOM! U.P. Up, up, up, is a word that you spell with a "u" and a "p". (hysterical laughter from the back of the car) Seriously. U! P! A word!
What choice do you have but to laugh along with them? It doesn't last long.
