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. Dirty tactics are employed by Mr Malone - he steals Ms Parfitt's coffee supply, so she's super-sleepy and unable to teach and tries to find out how she produces real smoke from her model volcano in class - almost getting himself blown up in the process.

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. It backfires - she eats disgustingly in his presence intending to shock him, but he doesn't even notice. By contrast, Ollie is sick of being treated by the others as one of the girls and Rob agrees to teach Ollie to be more 'boy'. Show less
