**In many jurisdictions the fist can be considered a weapon if the perpetrator of the assault is trained in the use of their hands (e.g.: martial arts instructor or high-ranking 'belt' - a professional boxer or wrestler - military trained and skilled in the art of hand-to-hand combat (i.e.: Navy Seal or Army Ranger) - etc) it is conceivable that the charge could be enhanced to reflect this ability to inflict pain, injury or death by their use.**
Saying *talk-to-the-hand* might get you 20 of hard time. ;(
