Ms Perfect

History teacher Mr Malone is jealous when new geography teacher Ms Parfitt arrives on the scene and all the pupils are excited about how brilliant a teacher she is. When it's announced there is not enough money to fund both a geography and history field trip and the most popular trip will be the one that gets the funding, both teachers go head to head in a fierce competition to get their field trip chosen. Meanwhile, Lily is complaining Rob is too 'boy' - she finds his boisterousness and burping gross and decides to give him a dose of his own medicine.
