I've been keeping this to myself for a while now. Didn't want to share ;P
Kinda bored and depressed right now though after my raid fell apart in Dragon Soul at the boss I needed. So I thought I'd share now.
THIS HERE LETS YOU SUMMON A MILLION (maybe more) YAKS!
Why is this not considered useless?
A.) They are annoying as hell. A swarm of yaks that follow you around and make loud smacking sounds when they hit you. Good for bugging people.
B.) You can use it while stealthed. No one will know it is you.
C.) If you are flagged PVP, they are attackable. Picture this.. You're in a pvp situation.. Then all of a sudden you are LOST to your enemy in a huge group of yaks! They can't target you any more! You're lost to them!
Now. All you have to do is this. Obtain Ruthers' Harness from the Quest in Townlong.
Now, make a Macro that says ONLY this:
/use Ruthers' Harness
Put that in as many times as it will fit on your macro.
Then fill your entire 1234567890-= bar with that macro.
Now proceed to roll your face across the keyboard like this:
Attachment 11455
TAHDAH! You have a ton of yaks. Try to hit the same macro more than once. So you're pushing them all at least 2 times for more yaks.
It'll look something like this:

EDIT: As someone mentioned, if you do not wish to break your face on the keyboard, you may bind the macros to your mouse wheel. Those of you who have already face rolled: I am not liable for any damages.
