HELp!!!!! I AM TRAPPED!!!!!!? OK guys im in my bureau (bedroom converted to one at least)...

OK guys im in my bureau (bedroom converted to one at least) and I got up to travel get something to put away. I reach for the knob turn it and hear a clunk......... The door does not open out........ Lucky me I have a screwdriver and thieve the knob off to see nothjing....... The square piece that turns the lock is missing along witht the other side......

My observations:

The pins are on my side :D
The slanted part of the knob is facing away from me :(
I enjoy a screwdrive and several textbooks (which brand name very doomed to failure hammers I own found)
Pencils Pens and a small stapler.... A 2 L of coke and a camera.......
2 metal forks and a couple small thin nail.....

Any IDEAS!?!?!?!

Answers:    Hmmm.. you make a polite case for keeping a mini-tool tackle in an bureau.
Sometimes the pins in a door's hinge thump downward instead of upwards.
You could use the handle of one of the metal forks (or the screwdriver blade) as a pry tool to force the lock slider out of the doorjam surrounded by the frame.
Or, download Skype (if you don't have a phone) and variety an emergency call to a locksmith to come and take you out!

It's been a while... hope you get out ok.
