My favoritist thing in the whole world...

as far as the day job is concerned: the Project Manager popping up in my cube first thing in the morning to tell me that the estimates that I've done 8 times already have to be done again because the biz changed their minds again. Love it. Really. Even more than when my cube is filled with big human puppies having anxiety attacks about problems with their code (not directed at anyone on my friends' list who might be wondering, BTW :-).
