Ridiculuos Gear Fixing Methods

I've searched far and wide for the most impossibly ridiculously cheap ways to make fixed gear wheels.  Finally, and completely by accident, I found a thread on a forum (bikeforums.net) which covers all of the cheap and dangerous ways people lock up thier wheels.  Some methods includ bolting a track cog to a disc brake, and jamming an allen wrench in your prawls.  One person even suggests holding the freewheel to the hub with zip-ties, a method my room-mate used without brakes to get around for an entire summer.  Dangerous!
