The Queen's guards are notorious for keeping a straight face, regardless of what pesty tourists throw at them.

He steps forward smartly, stamping his feet and shouting: "Halt! Get yourself away!"

The tourist turned around, stunned, before scampering away as the Scotsman kept shouting at him to turn the camera off.
