Okay, on a serious note, if you can get something wedge-shaped to wedge between either the roof and door or window-frame and b-pillar, you might be able to get enough room to get some type of rod (a wire hanger might
not be stiff enough to pull the lock handle) inside the car to try to get at the lock handle. If you have power windows I would highly
forcing the window down, as it has potential to damage the motor, regulator, or both. If you try the method of wedging the door open a bit, put a towel around the wedge unless you want to damage your paint. Also, the weatherstripping is going to get damaged a bit, too.
Also, if you have AAA, I believe they cover getting a locksmith there to open your door in the event you lock your keys in the car.
