Lock Tricks

I have six locks on my door all in a row. When I go out, I lock every other one. I figure no matter how long somebody stands there picking the locks, they are always locking three.


Interpretation: This funny quote presents a clever idea that might possibly work: if you have multiple locks on your door and only lock some of them, someone who tries to pick the lock and assumes that all the locks are engaged will not be able to unpick them all (until, that is, they figure out that not all of the locks were initially locked).
