Program bugs are highly ecological because program code is a renewable resource. If you fix a bug, another will grow in its place. And if you cut down that bug, yet another will emerge; only this one will be a mutation with long, poisonous tentacles and revenge in its heart, and it will sit there deep in your program, cackling and making elaborate plans for the most terrible time to strike.
