There was this one guy, who suffered from horrible B.O...He was a nice enough guy, but he had very bad hygiene. He wouldn't cut his toe and finger nails....and they were extremely dirty. Sensei always paired me up with him when we worked some of our techniques....and almost every time he would scratch me accidentally.
