From the duo that brought you I Didn't Do My Homework Because. . . . A wacky story of a class-trip adventure that "will be popular with tall-tale fans" (Booklist).

Notoriously (and delightfully) unreliable narrator Henry is late to a museum where his class is spending the day. But he has a plan: He'll just catch up in one of the exhibits. That's not possible in these halls! With volcanoes erupting, dinosaurs charging, and secret stairwells lurking, reuniting with his classmates becomes a quest of outrageous proportions. Young readers will revel in this entertaining book's over-the-top antics from the celebrated international author-illustrator team behind Junior Library Guild selections The Truth About My Unbelievable Summer and A Funny Thing Happened on the Way to School.
