Stephen Brown was a very quiet lad whose voice broke over a period of years rather than weeks. So whenever he was asked a question in class, he would whisper very, very quietly in order to minimise the relentless piss-taking. The teacher would in turn get very frustrated and ask him to raise his voice.
"Turn your voice up, boy! What is your name?"
"Stephen ..." he would squeak in a shrill falsetto before slipping into a Brian Blessed-esque boom "... Brown."
Hence the birth of the Stephen Brown Game, the aim of which was to say "Stephen BROWN, keep your voice DOWN!" The first part would be rendered in as high a pitch as possible, before landing the "DOWN!" as many octaves below as one could muster. Usually played when Stephen was around to enjoy it.
