There was this one dev that I was working with on a Windows Mobile project. I found a bug and dutifully reported it, with repro steps and all that happy jazz...he came back with "Not my code". I dug further and found the resources involved (all owned by him) and replied back with my findings, to which he replied "Still not my code". I asked him how it wasn't his code when his name was all over it and he came back with my 4 favorite words ever "It works on my machine. Therefore it must not be my code". So, I grabbed a phone, took it to his office, installed the Mobile app (from his machine) and had him repro the bug using the steps that I originally pointed out. ... ... This time, he came back with "Well, that's not working right...but it's still not my code". :doh: Shortly thereafter, he was asked to move on.
