You ain't been finger-printed until you've been finger-printed by the U.S. Marshals. Took thirty minutes. They took prints from parts of my hands/fingers that I didn't know could leave prints, or even knew had prints.

Ball prints would be a tricky concept. I wonder if they've ever had to do that?

There was this weird documentary on some cable movie channel a few years ago. It showed the process they use to make porn-star branded sex toys.

They make molds of the actual erect penis and testicles for dildos, and molds of vulvas and buttocks and mouths for... I don't even know what to call them. Receptacles?

I'm not sure you can match them up to a person very easily... The process was very uncomfortable and took quite a long time.

Enhanced CRBs are good fun. I've actually got a small folder full of the things. I'm 99.9% I could, with five minutes of effort, come up with a cheaper and more efficient method of carrying out checks, but it keeps the civil service busy, so there is that positive outcome.
