While this does fall a bit outside of the mainstream sports, some people can get pretty worked up over their boardgames. In case this, that enthusiasm led to a stabbing death over a game of Yahtzee.
In case you don't know what Yahtzee is(your grandma is probably gambling her social security checks away playing it right now!), Wikipedia breaks it down like this:
"The object of the game is to score the most points by rolling five dice to make certain combinations. The dice can be rolled up to three times in a turn to try to make one of the thirteen possible scoring combinations. A game of Yahtzee consists of thirteen rounds during which the player chooses which scoring combination is to be used in that round. Once a combination has been used in the game, it cannot be used again.
Each of the scoring combinations has a different point value, some of which are fixed values and others of which have the cumulative value of the dice. A Yahtzee is a five-of-a-kind and holds the game's highest point value of 50."
Now that you have a general idea of what game was being played, let's move on to the stabbing.
Apparently, Mark Kelvin Allen was playing Yahtzee with his friend's, Reuben Barnett, girlfriend. An argument over the game arose, and Barnett's girlfriend went into the bedroom where Barnett was and closed the door. Allen wasn't going to let that stop him so he "kicked the door off its hinges", and went in a stabbed Barnett twice in the abdomen.
Wow, that must have been some game of Yahtzee, if it makes you kick down a door and stab someone twice, leading to their death. Not even Joey Porter and Levi Jones took it that far during their cardgame altercation.
