I think most high school sitcoms that lasted for
any respectable length of time had a QB episode or
two, especially if there was a stereotypically smart
or nerdy character, like a Steve Urkel or Tahj from
"Smart Guy".
If one throws in things like pub
quizzes, there are lots of British programmes that could
be listed. [One episode of "Thin Blue Line" had
Rowan Atkinson's character obsessed with his quiz
team.]

Imagining what it would have been
like if Kenneth Williams, Charles Hawtrey and the rest
had done a QB film. ["Carry on Buzzing", maybe?]
