Knife-Wielding Drunk Monkey on the Loose

First we saw a knife-wielding crab that don’t take any sh*t. Now a monkey video, also wielding a knife has surfaced. What would compel a monkey to do this? Witnesses in Patos, Paraiba, Brazil say this crazy monkey snuck into a bar, drank a full glass of rum and grabbed a kitchen knife. It all makes sense now.
