A suggestion made by a commenter on douglain's blog was to answer the questions truthfully for yourself and thereby find out which character you are most like. What a great game!
Some of the questions were a bit tough - do I have a roommate - well, yes, the guy I sleep with, but that's probably not what it means. Still. If I was a girl I would be Rebecca from Cheers, and if I was a guy I would be Jeff from Coupling (yes, the horny Welsh git).
