Today is the grandest of all sixth-grade days at Marcy G. Middleton Middle School: the Great Ancient Greece Extravaganza. So far, it's a herculean success, with kids wrapped in bedsheets performing onstage, a backdrop of Mount Olympus standing tall, and a giant cardboard Trojan horse ready to roll. But when the mighty stallion makes its debut onstage, Spartans are left speechless by the Great Trojan . . . Chicken? How, exactly, was the horse transformed? Did a competitive set designer or rival baseball team vandalize it? Perhaps the high school theater teacher introduced this challenge to test the students' acting skills. Or maybe this is all just a bad dream . . . Crack open a What Happened? book to investigate a preposterous mystery from four different perspectives. See what the witnesses gets right . . . and what they get hilariously wrong. Bet you'll never guess what really happened!
