So in honor of the start of school, here's a joke from 777 Great Clean Jokes:
Early in the morning, a mother said, "Son, it's time to get up and go to school."
"Mom," her son replied, nobody at school likes me. The students don't. The teachers don't. The bus drivers don't. I don't want to go to school!"
Mom then said firmly, "Son, you must go to school. You are healthy, you have a lot to learn, and besides... you are the principal!"
