"Mom, can you see my oovoola?" (Opening mouth really wide.)
"My OO-VOO-LA." (Again, opening mouth.)
With total exasperation, "YES! The little hangy thing in the back of my throat?!"
She keeps looking exasperated, while I continue to spasm with silent laughter. Just hearing "uvula" come out of a 3-year-old's mouth is hilarious.
