Whenever my boys ask for a peanut butter and jam sandwich, this is what they say:
"I'd like a peanut butter sandwich made with jam. Yum, yum, yum, yum, yum."
For those of you who aren't Raffi aficionados, that's a quote from his song about the beloved kids lunch. They don't always sing it, but they do speak it in rhythm. It's so funny.
