Inspired by this
thread, and an identical thread to this that I've seen on another forum I'm a member of, this is basically a place to list all those little things that annoy you. When something annoys you, get your arse onto KKW and list it here and vent your frustrations with your KKW family. Then feel better.
My choice for today (inspired by PD) would have to be knuckle-cracking.
