Walk-ins are always a favorite of mine because those that I have encountered have had extremely memorable resumes but not in a way that any job seeker would want. My all-time favorite really did get attention from junior designers on up to the director because it was such a laugh. I really regret not making a copy of it. It was a one-piece resume and portfolio teaser delivered in person by a hopeful job seeker who did not even want to spend more than 30 seconds in the office (I offered a dime tour and I was shot down!). Anyway, the document was a single B-sized printout rolled up and held with a rubber-band. Unfurling the paper exposed an apparently random assemblage of images, sketches, and renders with a list of key interests and character traits that included an interest in sexy design, an interest in sex, and character traits of virility and sexiness.
I am 99% sure it was not a joke.
