Thanks to Paul at Impolitic Eye for this one: taking the What's Your Type? quiz will result in an answer like "Helvetica" or "Comic Sans"... mine resulted in:
As an added bonus, it seems to do a compatibility test with other fonts. (I apparently go well with Helvetica and Mistral -- Brian?) EDIT: this is actually more fun than a compatibility test: if you put two fonts together, it shows you a short video of the two of them having a drink together. I highly recommend viewing Helvetica + American Typewriter. IT WAS A DIRTY PONY!!!
