Agreed. I always had trouble connecting the two. I wonder if the Professor on Gilligans Island was a Kenpo 6th Black, lol.I think in some circles it's not uncommon for "Grandmasters" to "sign" for each other (sign a rank certificate) as a tit for tat, which explains why you get people with 8th Dans in 10 different arts. Not worth the paper it's printed on, but it sure looks good.
Personal peeve of mine: Instructors who use the term "Professor" to describe their role as a martial arts teacher, but having ro relationship with any university.
