I enjoyed this video of Sheila Eglen's rank test very much. Congratulations Ms. Eglen.
Though I really enjoyed this vid, especially the music and the choking laugh at the end, I don't really get into abusive rank tests. Any instructor worth a hoot can look at a student of their art for fewer than five minutes and tell their approximate skill level, so this isn't really a rank test. This sort of thing really only serves to demonstrate to the student that undergoes it that she is tougher than perhaps she thinks she is (which isn't a bad thing to be taught).
This reminds me of the horror stories about some of the surprises during one of my old karate instructor's sandan test. Allegedly, during her execution of various kata and techniques, an observing black belt fired a shotgun into the air to panic her. At another time during the test, an observer crept up behind her and garroted her with a rope.
That was one tough lady.
