If you have a brother, or two, like The Thirsty Beagle, you’ve probably had your share of spats and disagreements over the years. Brothers can really go at it, especially when they’re younger. But with age comes wisdom — hopefully — and those wedgies and noogies and headlocks fade into the past. Or do they? If you are 45-year-old Kenneth Mullins of Lutz, Fla., who says you can’t punch your brother and smash a glass over his head? That was the scene that carried out Wednesday in the bathroom – yes, the bathroom – of Mullins’ home as him and his brother got in a fight over — wait for it — the last beer. Even worse, it is reported Mullins repeatedly slammed his mother’s arm in the bathroom door as she tried to intervene in the fight. Now don’t get me wrong, having only one beer left is a serious issue. But allegedly assaulting your brother and mother over it? Going to jail over it? That better have been some kind of gold-plated, weather-controlling, keep-you-warm-in-the-winter magical bottle of beer.
