There was a young kid (probably 9 or 10) at my dojo who just wouldn't shut up. My instructor kept threatening to sticky tape his mouth shut...so after a couple of weeks of threats he actually did it. Went into his office during the middle of class, got a big roll of duct tape and taped the kid all the way around his mouth and head.

LOL! better hope the kids parents are not lawyers
YAY pepto bismol! No... not... kryptonite
