14. The Stinker (I was sitting right next to this guy in this example)
This guy is total trash. His baby does its business, so what better thing to do than change his diaper in his own seat!?! The smell proceeds to stink up the entire cabin; excrement spills onto the floor; and even F/As can't walk around to do their duties because of the horrid stench. When you ask him if you can lower the arm-rest (ostensibly to relax, but actually to provide some separation), he asks, "Well, who's gonna use it? Me or you?"
