Harvey thinks school is the most boring place on earth - and so he and his friends devise a way to help relieve their boredom. Lessons are actually quite interesting when you have more at stake than just whether you'll get through it without being sent to the head. Harvey and his fellow gamblers start to bet on how many times the supply teacher will give a nervous twitch, how often the Head will blow his nose and lots of other possible outcomes. All of a sudden, school is fun - but then the gambling craze starts to spread and Harvey realises it's all getting out of control... A brilliant subversive look at classroom pranks and what goes on under the teacher's nose.
