Siblings Fight Dirty
Great story about two brothers in Florida arguing about something when one decided he'd heard enough from the other--went outside, uprooted two of the pot plants they were growing (family business?) and proceeded to pummel him...to the point where the yelling caused neighbors to call police. Cops show up and separate the two...and arrest them both!
Doesn't that bring back the crazy argument you had with a sibling? We've all had them...and they are epic, point-of-no-return nuts.
