I've done it in my benz once too, not too hard. If its a Brake stand like I think it is. Keep the foot on the brake and keep giving it gas until the wheels breakloose, then keep applying the gas. Do it on a straightaway and release the brake when you feel like launching the car.
I take no responsibility if you mess up the car though. I have done it once for a short 10 seconds, and don't intend on doing it again. You have no idea what it could be doing to the suspension and or brakes. or the the car for that matter.
