Early one morning, a mother went in to wake up her son. "Wake up son, it's time to go to school!"

"But why, Mum? I don't want to go."

"Give me two good reasons why you don't want to go."

"Well the kids hate me for one, and the teachers hate me too!"

"Oh, that's no reason not to go to shcool, hurry up and get ready."

"Well give me two reasons why I should go to school!"

"Well, for one your 52 years old, and another, you're the Principal!"
