my boss was getting his done for some nuke stuff.
When I was interviewed it came to the sexual stuff and my reply was "well his nickname is Chai Chai". Who was in London zoo at the time.
interviewer leans forward and says "so he has a preference for Chinese ladys?"
"No... he has the sexual prowess of a giant panda" was my reply.
My thoughts that the interview was confidential to the person being enquired about proved to be false.
