Once a Pound a Time,

A student of mine started a story with this phrase.  She's 18.  I cannot decide how I'm going to break the news to her.  I was mad at age 3 or 4 when Mom and Dad told me that nayonnaise is really mayonnaise. (So I just ate twice as much!)  

I wonder how much of what I know and understand began with once upon a time?
