Gordon is frustrated that Ted, the school bully, gets away with pushing people around - including Gordon! So when he spots an advertisement for Mr World's muscle machine, he's immediately curious and decides to send off for one. 'Don't be impatient' says the instruction booklet that comes with the machine. 'Muscles don't grow in one day. Take it bit by bit and you ll be surprised at what happens!' And indeed he is. In fact, Gordon's surprise, as well as his muscles, just keeps on growing!
