This is silly but its true, in Guam you have to register yourself as a deadly weapon if you're an expert in the martial arts. What they define as an expert is anybody who has "completed at least one level of training therein and shall have been issued a belt or other symbol showing proficiency in such art."
‘These hands and feet are registered as deadly weapons … in Guam!’
