My craziest bug was a Java clock issue. If you had some specific model of motherboard, calling System.getCurrentTimeMillis() repetitively could actually make your system clock run faster. I mean, actually CHANGE the system clock. For real. Like 10% faster. That led to veeeeery interesting issues related to timing on the game I was working on, and of course it me took days before I would even think that my problems could be caused by the time actually running faster on different machines.
