Pie in the Face Motivation

My kids at school are so done with school work after such beautiful weather and daylight forever in the evenings. They are not focused nor do they care about school. We have some important tests to take and the scores really matter. One of the teachers came up with the idea that if 95% of them go up on their score, the class can throw a pie in her face. So, I decided to offer that to my class. They loved it. I added that if 95% reach their target goal, each of them can throw a pie in my face. I'm so hoping I get pied. One little girl innocently asked if they can eat part of the pie. Sure, you can lick my hair clean.
