I needed a quick birthday jingle for a data geek; so I tapped out this to sing after the Happy Birthday Song:
Age plus plus; update; commit;
The years spin round and round.
Age plus plus and so it goes
We're happy you're in town.
I assume programmers prefer age++ to "Happy Birthday" since incrementing the age variable is more efficient than legacy birthday systems.
Anyway, geeks seem to appreciate the age plus plus bit.
