Keep trying. Their phone lines are usually really busy.
If you want to cheat a little, film yourself with a 35 mm nikon- film, not digital. Then, sneak it into the youtube corporate office. If you put a little youtube logo on the box, they'll think that one of their employees left it their and they'll put it up. However, it is easy to be caught doing this, so I'd suggest keep calling and wait till one of their film crews can come out.
