World of Warcraft Hacked

I have officially hacked Blizzard Entertainment's newest game, World of Warcraft! Although it isn't much of a hack but more of a MOD, I changed one of the phrases the Human Female characters say when you type "/flirt" to one of the phrases the Night Elf Female character says. The night elf one says,  "Sure i've got exotic piercings." Though this is a change, it only effects the computer the change was made on.
