Wine Lovers Will Mourn Over Specsavers' Hilarious Ad

Specsavers has brought back Daniel Kleinman to direct the latest spot in its "You Should've..." campaign.

Set in the idyllic Provençale countryside, the ad shows a plumber going into the cellar of a stunning French chateau in order to drain a faulty boiler. He turns the tap, and tips many buckets of fluid down a sink until the boiler has been emptied.

After the plumber leaves, the chateau's owner walks back through his property and hears the same radiator rattling loudly, just as before.

He realizes with horror that the plumber tapped not into faulty pipes, but something even more precious to him, which we won't spoil here. The oblivious -- and visually impaired -- plumber, meanwhile, is driving merrily through the countryside, greeting farmworkers as he goes.

The spot is promoting the U.K. optician's new online booking system for eye tests.

Kleinman also directed another spot in the long-running series, featuring angry chef Gordon Ramsay.
