I work with so many crazy people that I never even know where to begin in the co-worker thread.
When I first met the guy who got fired, though, he was standing at his desk chugging water straight out of a gallon sized milk carton. Like, he just held it in one hand like it was a coffee mug. He was basically a body builder. Big muscles. He put the water down on his desk, said "wusup", shook hands, and then went directly back to chugging.
The second time I saw him was on Friday of that week. He was out in back of the building, standing behind this enormous grill loaded with burgers and brats and dancing to whatever music he had on. He was occasionally calling for someone to throw a football to him and then he'd throw it back really high and far. He was wearing shorts and flip-flops and these gigantic sunglass that weren't ski goggles, but the lens in them was like the size of the lens in ski goggles. I later learned that they were several hundred dollars and Italian.
