One of the guys at our office here in Cairo is a kung fu teacher.
He found out that I train as well and asked what style I told him BJJ and he said "Yes I know this Jiujitsu I know how to defend against it"
Then went on to tell me how much he likes JKD as well and about how he once beat 40 karate guys for another school at one time. "I put my students behind me and told them to come on and fight, then I beat them all with only kicks to the groin and neck. After the teacher from the other school asked why I kick them in the groin and neck and I tell to him that if I am not kicking them there then I am killing them!"
