A stupid comment, which is swiftly followed by the swift hand of STFU to the back of the head. Dave has little to no tollerence for Harold's nonsence and will useually be the first one to repremand him for it, physically. Glenn however is slightly more tollerent towards his little brother's behaivor and will verbaly reprimand him if he crosses the line. Well, watch in amazement as these guys begin to fight in a movie lobby.
