Mac McGerp is the best burper in Withersberg. In fact, he's a famous champion burper - he can even move objects with his burps! His best friend is Lido Katz and they have great fun together. Until, that is, Mrs Goodbody arrives at school. She is their sixth principal in as many years and she is by far the meanest. Mac is about to be kicked out of school for his award-winning burps. And if Mac gets kicked out, Mac and Lido's dream of someday owning the Burp and Surf shop in the Bahamas may just go down the drain. A hilarious romp through the perils of - Eeerrrrp!
