the kid (19) went in, told the guy teaching he had years of BJJ training, but couldnt remember the name of his teacher. Instructor told him he thought he was making it up, the kid then said he was a grappler and would grapple anyone there......during the kid's class. 13 year old steps up, they grapple.
