    #define DEFINE_GUID_RIGHT_FUCKING_NOW_DAMMIT(x) // ... stuff

I wrote that at 2AM once when I was at a start-up. I'm not proud. (Well, okay, I am).

A couple years later (after the start-up had imploded) I was asked to consult to fix issues that cropped up in the code at a customer site -- they'd bought an SDK and were having problems. During a walk-through of my fixes I found myself explaining that line of code to a suit.

The suit nodded. "GUIDs. Yeah, getting those right is tricky."

[That consulting gig was sweet; short, but I was able to charge $300 an hour. I should have charged more, they basically didn't care.]
