I have a very vivid memory of one day in the dojo with my teachers. It was just me and them. We were working on kokyo tanden ho and Garth sensei was trying to teach me how to relax and just move up my center. So as I had a hard grip on both of his wrists he proceed to sing and perform the itsy bitsy spider song.
Not sure if I fell over from laughing or from him actually throwing me. maybe a bit of both. But it served very well to teach me what he was trying to illustrate.
Another is kokyu nage where nage just reaches down to pick an imaginary flower lift it to their nose to smell it and the tosses it away, all with the hand that uke is attached to.
