Magic words

Yesterday, we were with a group of kids and preschool-level teachers and the teacher said "What's the  magic word?" as she was getting ready to hand out marshmallows.

Lydia looked at her and said "Abracadabra??"

(And, yes, she knows how to say "please" and "thank you"  But, in our house, those are polite words, not magic words.  Just a pet peeve of mine.)
