When I was in the AF, I had to be a part of the team that administered the "whiz-quiz". One guy that got hit with it had diarrhea so bad he couldn't piss! It was like any water drank was immediately diverted to his colon! He had to be there the whole day until one of the higher ups finally had him go to the hospital to get a blood draw done.

And another fun fact about it, when the admin types (called the orderly room in the AF) would call, the way you knew it was someone getting tagged was they wouldn't say why. Any other thing they would call about, it would be like so and so had to go over do/sign/whatever. When it was 'quiz' time, they would just say so and so needs to report...
