FMA: T-Shirt Story
True Story

A friend was wearing a FMA T-shirt while standing in line in Chicago. Behind him was an old Filipino man that asked him if he studied Filipino Martial Arts. They started up a conversation and the old timer invited him to come over to his house and learn their family FMA escrima system.

If I remember the story right, the escrima system didn't even have a name, it was just something they learned father to son. It turned out to be a really cool knife fighting system. It was unlike anything he had yet seen. 

One day he had the chance to meet the man's adult son and my friend got a chance to see father and son go at it (knife fighting drills) in the kitchen with live blades. These guys weren't martial arts teachers or known at all in martial arts circles, the old guy was a retired fireman.

He attributed the whole experience to that one FMA T-shirt.
