3Po: Mama, what are tongues for?
Me: Well, tongues are for tasting things -- tongues are what help you taste sour, sweet, salty and bitter. They're also for speaking. You wouldn't be able to speak without a tongue.
3Po: Is that all?
Me: I think so. I can't think of anything else.
3Po: I know one other thing tongues are for.
3Po: They're for licking lollipops.
