James Corden has surprised workers at a London estate agents with a motivational speech.

In the guise of his Gavin & Stacey character Smithy, Corden isolated a number of members of staff at the Greene & Co branch in West Hampstead as part of the light-hearted routine.

The eight-minute video (via The Sun) sees Smithy tell one employee: "How can you sell homes when it looks like you're homeless?"

He continues: "Goldschmidt's? Gold s**ts! Foxtons? F**k you! You are an unstoppable machine.

"I am proud to say that I, Smithy, when it comes to property, will definitely consider you as one of the three quotes I will get."

He concluded his speech by saying: "Greene & Co? Do you know what I call you? Green and go. Go forth and sell houses. Do it better than before."
