In the redridge mountains, there is a quest called "Saving Foreman Oslow" that requires you go into a cave, click an orb with wings, and it gives you an item [Ettin Control Orb]. This item is the money maker. It allows you to take control of one of the huge Canyon Ettins roaming around. Normally when you use it on them, and they become your pet, but if you go out of the zone, they disapear. HOWEVER if you kite them out of redridge before using the orb on them (specifically into elwynn forest) it will allow you to take it to stormwind (you can mount up and it will run 310% on the ground under you) take it into stormwind, and run back and forth. When it steps it shakes the ground within like 30 yards, the Ettin is about three times as tall as any character, and will help you fight if you wish. Lasts for ten minutes or so before it disapears and you have to go kite/tame another. I have done this multiple times, and it has always worked.
there are plenty more where this glitch came from.
