An expletive-laden argument broke out on a London street after a Lamborghini Murcielago LP640 driver began revving his supercar for the camera.
The Lambo driver was apparently asked by the person filming to clear the 6.5-litre V12's throat. He obliged... and an angry man suddenly appeared to, um, "ask" him to stop revving the 464kW beast.
A few verbal volleys later a woman joins in and asks the Murcielago driver "who do you think you are?".
Personally, we think the Lamborghini sounded pretty good.
