As Emma sits in the backseat capturing the episode on film, the boy in the driver's seat is tasked with turning the ignition key. "But only when I say go," says Dad, who hopes that wiggling one of the HT leads will be enough to get the car to start. Of course there's nothing funnier for a kid than seeing their dad suffering, so a premature turn of the key results in Dad wheeling away in pain having received an electric shock from the high voltage cable.
Accidents happen, so Dad chalking that down to a genuine mistake is fair game. However clearly this is no accident. At the next opportunity the son sends yet another bolt of electricity to Dad who lets out a yelp of pain.
