Some CEO dumps a logo on my desk and tells me to make a new one with an entirely different text but using the same font. Me: "Sure. So... what's this font?" Him: "How should I know? That's your job innit?"

It could be a custom job; however, I rate that as unlikely, given the subtleties -- the left and right leg of the "U" are of slightly different widths, and the "N" has some surprising curves I just know I've seen before (perhaps Friz Quadratish?). OTOH, I'm not too wild about those "E" and "F"s. Still, I'd like to know.
