It has to be. Case in point, look at the list of current residents and what they do. A lot of those jobs require business formal wear (read: a suit) at least part of the time. You can get great suits under $500, sure, but as someone who recently went new suit shopping, $500 doesn't get you much.

Possibly. The author does himself/herself a disservice knocking down some really low-hanging fruits and almost cult-like points. I stumbled across the original posting actually and thought it deserved a mild chuckle at best.

To me, it's Disneyland meets Aleksey Vayner's "Impossible Is Nothing" video CV meets "her knees are too sharp" (the ridiculous laundry list of requirements).

I think that it's real.

That said, the part about "explicit lyrics" made me laugh. Programmers like for things (at least, code and documentation) to be explicit (in the original, non-euphemistic, correct meaning of the word) and generally have no use for the implicit use of "explicit" to mean "vulgar".
