Toddlers' Drug of Choice

We could hear the screaming from a room away.  "That's our kid," I said to Tony at yesterday's pick-up.  Jill had stuck her fingers inside the door while one of the teachers was closing it.  She was very upset - as was the teacher - and the other kids reacted. 

So what got them to quiet down and all sit around the table almost immediately?  APPLE JUICE in a small Sesame Street-themed box picturing Big Bird.  "It's like liquid crack," Tony whispered.
