Hilariously illustrated, a cautionary story about a girl with an amazing talent for burping

On an ordinary morning, in an ordinary room, an up-till-now perfectly ordinary Bertha does an extremely extra-ordinary burp. A burp so extraordinary, it knocks things over--including apples off of trees and even her teacher's glasses off his face! When word of her humongous burp gets out, she is asked to perform at the school concert, and from that point on Bertha's fame is assured. TV, recording, and film offers flood in. But burping can be a dangerous skill . . . is her new found celebrity stardom all just a lot of hot air?
