Hi Gornall -
Assuming for the moment that the video wasn't a joke, what did you find objectionable in it from an Aikido perspective? Are you aware of what Graham was trying to accomplish in the lesson?
I'm relatively new to aikido but have studied other martial arts for getting on 31 years and from my point of view I failed to see any martial application in the exercises being done in that video. Maybe I'm looking at it wrong but in the classes I've taken in aikido in the past and again over the last few weeks I've never seen said exercises done in any classes I've attended either.
Mind I didn't watch the whole video as from what I did see I didn't see the point.
