Profile
When Mr. Brown reports to Miss Courtney's office on his first day, she tells him that Mr. Warburton, his predecessor, taught the EFL class for a month before going insane. He climbed out the classroom window, stripped himself naked and sang "I've Got a Lovely Bunch of Coconuts" on the school roof, leading Miss Courtney to nail the window frames down in order to prevent such an incident from happening again.
