School's out for summer. School's out forever. Those are the infamous lines from Alice Cooper's song "School's Out" popularized in the 90s movie "Dazed and Confused."
For millions of children, forever is only 10-12 weeks. Then in the immortal words of the Four Tops, "You gotta go back, back, back to school again."
Somewhere between the time the last bell sounds for the school year and the alarm clock rings signaling the first day of school, the knowledge acquired over the past nine months begins to seep out of children's brains.
