Watched House now
The cop guy seems to be the type to look for trouble. I don't blame House for starting it - he merely replied to the 'I waited two hours out there'. He's the professional and if hew says there's no need for a test than he probably knows what he says. Yes he could have phrased it nicer, but in the end the cop was the one to trip House. Was he really expecting everything to be back to norm after that?
...Poor Cuddy, actually. Wilson... well... the whole 'you and me??' part was hilarious
