Who thinks of this stuff?!?

I discovered a colossal time-waster on this site, and I've been, well, wasting time on it all afternoon. I've barely scratched the surface, as I've been preoccupied with just changing the homepage repeatedly (there are 22 variations). I swear I've seen this part somewhere, but can't remember where. But seriously, who are the people who think up this stuff?!?
