The fish represents a certain aquatic member of government, feeding the hamsters (I assume this is a correct Hampstead demonym, yes?), into his free school machine, which grinds students into a pulp and injects useless latin into their systems.
As a sidenote, I'm a new member of the Trash, I've been asked to draw a few comics for it, to appeal to our illiterate audience.
The aim of this comic is to disassociate ourselves from the Ham and High, who have been using Trashgate as a vehicle to voice their distaste of state schools. When it comes to the Ham and High questioning the legitimacy of any plebducation using our work, we must remind ourselves that we really wouldn't be better off inside a free school, and we should give credit to the head for not letting that already happen.
DISCLAIMER: This Hampstead Trash article is purely satirical, that uses crude humour to satirise the faults, flaw and misdoings of the school.
