SMACK! Well, not really but funny none the less...

The developer who was responsible for investigating the bug decided to use this "signature value" technique. It is often the case that, for throwaway temporary signatures like this, you will use your own initials as the signature value. This is partly egotism but mostly just lack of creativity. But this particular developer had a better idea. Since he had a pretty good idea which component was corrupting the memory, he used not his own initials, but the initials of the developer responsible for the component he thought was the corruptor! That way, when that developer's component corrupted the signature, it'd just be corrupting his own initials.
Of course, when the developer of the suspect component saw this check-in, he felt kind of insulted. After all, his friend just accused him of corrupting memory.
