Want to make Joy double over with giggles?
Take a pinch of shredded parmesan cheese between your fingers and let it sprinkle down over a plateful of food.
Funniest thing in the world!
Even better is that she gets all of us to laugh with her! She anticipates the delight, waits for the cheese to come out of its container, and signs "more" through her gales of laughter. (It's a good thing we like parmesan!)
I don't have a clue why the sprinkling of parmesan cheese should elicit such a reaction, but the giggles are simply priceless.
