Whoah. I never had that bit LOL. You got special treatment :) They did an eye test and made me get some vaccination records from when I was a kid.

The craziest bit I found was the GC interview where they test your spousal relationship. Expected questions like "What side of the bed do you sleep on?", "Who takes out the garbage?" -- instead they spent 30 minutes interrogating my wife about the military base she was born on and spent the first 6 months of her life at ("Who was the commanding officer at the time?"). It was like something out of a KGB script.
