you'd come out flying and give a judo-chop to the first figure you'd see!
or....
You need to get a visual first without making a sound, and an item which can be used as a stabbing weapon (must have a secure handle which your palm can rest against, such as a screw driver) and also grab something to use as a decoy such as a towel. You can then decide to attack by stealth or speed. The main thing is to open the door with minimal noise keeping low and against the wall. If you are spotted, then you must throw the decoy towards the person and run in a circular motion with some slight change of direction to make movement predication more difficult. When close to the target, you slide towards them and thrust the stabbing weapon from a low position upwards and into their kidney ensuring your palm is supporting the base of the weapon so as to achieve penetration. You twist the weapon to open the wound, pull it out and fling it away, and then stand up with your rising elbow covering your head and when at standing height use your other palm to strike their jaw closed. It is then important to maintain their jaw closed and apply pressure to prevent screaming, though if you've stabbed them correctly the pain will do most of the work for you.
Well, at least he didn't do that to the maid.
