You know those sketches the police put out of suspects to help catch them? Do they ever look like real people to you, and when they catch the suspect, do they ever really look like them? I'm sitting here laughing because they just showed on TV a sketch of some serial rapist, and had the FBI sketch artist who drew it holding it up, and would've sworn it looked a whole lot like the guy drew a self-portrait! When I was in grad school, the bio office had a whole bunch of sketches up on the wall (the building was bordering a BAD area of town, so there were a lot of local robberies, etc). I just sat amazed one day that they all looked the same to me.
