Armory Gender Change

1. Drink Pygmy Oil - Item - World of Warcraft until you become a Pygmy
2. Now eat a Savory Deviate Delight - Item - World of Warcraft
3. Log out of your character
4. Check the armory and you should be the opposite gender

You're now a male/female on the armory. Lets you see what your char would look like as a female in case you're wondering what it would look like. I'm sure there's more uses than just that but it is of some use.
I don't have any female characters to test this out on but I'm going to assume it will also turn a female into a male.
