Re: Oh $#!t moments...
I remember when I used to do Ukemi for my first Sensei. He had this really bad case of skin allergies (eczema I think). Anyway, he usually gets some scales on his skin and these "scales" would fall onto the mat.
So whenever I do Ukemi I always do my best to avoid the scales on my way down but as I get pinned from a pivoting Ikkyo I sometimes find myself "face-to-face" with the eczematous scales...and I always say Oh $c#les!
