There's a reason this guy's a valet and not, say, a NASCAR driver or even a cabbie.

This is video of a valet at a hotel in Monaco trying to rev the engine of a Lamborghini Aventador. Problem is he forgot the car was in gear, sending him lightly into a vehicle right in front of him and managing to cause notable damage to the $800,000 car.

Don't you just hate when bad things happen to something as amazing as a Lamborghini?

And lucky for him the whole thing was on video, so he can't deny he did it.

We say he's the worst valet since this guy.
