At my past couple of companies, we've tracked any births to the core eng team in the build system: you can go to the top of the build tree and type "make babies" to see who was born and when.
You also have to have clearly defined ground rules, and it helps to have contingency plans for unexpected events.
In the event the relationship receives a SIGHUP, you can only hope that it terminates gracefully- nobody likes a zombie relationship that's waiting on closure() that will never return due to the sudden absence of /dev/love.
The moderation on this whole thread has been incredibly entertaining to watch. I'm sort of surprised this joke post got beaten down and the sarcastic post got elevated.
While I would never hope for or wish unhappiness on some one, I'm afraid the next punchline to this joke is an update in the future in which the thanks line is gone (presumably for his ex-wife).
Such comments always make my day, and I am always with an eye looking for them. Most of the time I feel like someone that's stuck in a jungle and finds marks of previous ... activity, "Hey, I am not alone".
Such acts make privacy concerns about Facebook et al. look trivial in comparison. Pulling last weekend's drunken photos or wall messages off your profile is not that onerous. Good luck tracking down all the forks of your git project and tampering with their history!
