Gooney Bird Is So Absurd by Lois Lowry

If you haven’t read the Gooney Bird Greene books, you have to give them a try! This is the latest in the series, and Gooney Bird is still setting the trends in Mrs. Pigeon’s second grade class—this time, wearing ruffled underwear on her head to warm up her brain for poetry writing. Soon, everyone is wearing underwear on their heads--they need to warm up their brains to help Mrs. Pigeon through a very tough time.
