Who was your worst coworker?

My current coworker who has the same position as me but does nothing but sit there and stare at his phone all day. I do more work than him in 10 minutes than he does all day long and he is getting paid $3/hr more than me. On top of that, he has a dead tooth or something because it always smells like shit near him. By midday, the entire room will stink of his shit breath. I assume he's never heard of tissues because he blows snot rockets onto the walls and floor daily. He takes half an hour bathroom and smoke breaks. 2 each daily so he is on break about 2 hours a day not including his lunch. Plus he takes that long breaks at the busiest times of the day. He basically works an hour or less a day.
