This humorous picture book answers the question all kids want to know―what do teachers do when the bell rings at three? Once the students go home, teachers finally have the run of the school. They skate down the halls, have a food fight in the cafeteria, even mix up wild concoctions in the science lab with disastrous results! All night long, teachers are busy goofing off at school. Kids will never look at their teachers the same way after reading this book!
