I wonder what sparked off the headline 'Ohm James' in The Sun newspaper last week? The story reported that Rolls-Royce had unveiled its first electric car, a £1m Phantom EX102 at the Geneva Motor Show.

The headline plays with the fact that an ohm is a unit of electrical resistance and mixes it with the popular English idiom, 'Home James,' which is often used when telling a driver of a vehicle to start driving, as if you were issuing an order to a chauffeur.
