Instructables have an article up on how to keep your bike from being stolen.

I am a particular fan of steps 9 and 10:

Step 9 – Trying to make your bike unridable

Fixed gear riders advocate fixed gear bicycles as a method of this, that they are somehow more secure because they are harder to ride. They are forgetting that due to the unbearable popularity of fixed gear bikes, they have become incredibly attractive targets for theft. 

The accompanying picture is of a Bianchi Douchebag Pista with chopped flat bars. The author says:

I love the reflectors on the pedals, by the way.  Nice, really nice.

Step 10 advocates ratting your bike to make it look ugly.

even major bike manufacturers have taken to making intensionally ugly bicycles. Please, a bicycle should be a thing of beauty, make the madness stop. 

The accompanying picture?  A particularly nasty specimen of the Langster, London Edition.

Pretty spot on if you ask me.
