The man who walks into the bar with the shard of glass has a gambling problem. He was in his home, when two men bust in the front door and begin to assault him.

Upstairs, his only son hears the racket and runs down to assist him. He gets the best of the smaller man then turns to get the bigger man off of his dad. The struggle ends up with the man falling on top of the son through the glass table. Thinking quickly, the son takes a shard of glass and jams it in the man's neck. He rolls the man's body off of him, breathing heavily he says "Dad, I'm going to jail."

Not willing to spend the rest of his life away from the only family he has left in the world, he takes the shard of glass from the man's neck, calmly makes his way to the neighborhood bar and stabs the man to which all his gambling debt is owed.
