Testing is important. Like when you test your server program that forks another program in the privacy of your home, only to discover you put the child code where the parent code should have gone and vice-versa.
You and your wife can have a laugh about it, instead of getting reamed out by the client or your boss for fork-bombing the server.
Sucks because it's still a stupid mistake, but at least I managed to minimize the amount of shit that would have otherwise landed on me.
