The setting is a children's party, in a backyard complete with pinata. A small child hits the pinata with a bat (or stick), the pinata explodes, and celery comes pouring out. The children yell "celery" and rush towards it. Craziness ensues, and the children run away, clutching their celery, looking sort of like teeny savages, brandashing teeny green spears.
The voiceover says "if only it were this easy to get children to eat healthy. Since it isn't why not start the day with Florida Orange Juice." Or something like that.
I nearly fell out of my chair laughing.
Also, as an aside, I could not love workout/fitness shows more. Biggest Loser, Celebrity Fit Club, the new Shaq show. I love them all. Something is clearly wrong with me.
