Pie

Cash and Legend are playing happily in the back yard, when Legend turns to me and approximates the word "hungry".

Me - "Are you hungry Legend? Do you want a snack?"
Legend - "Hungry. PIE!"
Cash - "PIE!"
Me - "I don't have any pie. I can get you something else..."
Cash and Legend - "PIE!!" Giggles ensue.

The boys continue to yell, "Pie", and giggle at each other until I show up with oranges and granola bars.
