@contrex,
I know, I lived there for a year. Weirdest place I've ever been too. There was a secondary and two primary schools, but the average age was 70. Mary Whitehouse was from that neck of the woods, backwards, reactionary, right wing and highly religious.
At every school my daughter went to she was a good kid, when she was at Frinton she was the bad one. I was once called in to see the headmistress because some of the parents complained after hearing her sing, 'I'm smarter than the Devil.' She was copying Homer from the episode where he sells his soul for a doughnut.
Nowhere else would this be a problem let alone one where parents had to be called to the school.
