It seems that you can pick certain types of barrel-style locks with a ball point pen...
I just managed to do it on a laptop lock here..
Others that are rumored to be vulnerable:
Kryptonite Bicycle U-Locks (Yah the ones everyone says are the best)
Many motorcycle disc locks (Kryptonite makes some of them)
H-D ignition cylinders. :O
You just separate the pieces of the pen and jam the open end of the pen cylinder into the lock and twist/bend it around and if you're lucky it will hit all the tumblers and the lock opens.
Just something to watch out for... sell your kryptonite stock!
