I still recall how, as a fresh-faced, young gamer just getting into the newfangled realm of online multiplayer, I got absolutely got in Everquest when somebody told me you could get a numeric representation of your current experience points by typing "/ex".
It was actually short for "/exit". And in those days, it took a loooooooooooooooooong time to relaunch the game and get logged back in. Learned a valuable lesson about human nature that day. It has served me well.
