This was only a little bit funny, but mainly embarrassing.....I was training with my Sensei's wife, and part of the technique (forgotten which one....) was an uppercut to the chin. I swung my fist upwards, aiming diligently for her chin......but her boobs got in the way. She was a big girl in the boob department, and my hand smacked into them. Almost twisted my wrist! All she did was look at me and ask if groping was part of the technique!
