Hi, long time lurker, just found something interesting. Haven't seen anything similar so let me know if its a repost.
Anyway, I was messing around on the Skybreaker in Icecrown and found this out. It allows you to /dance, cast spells, do whatever as long as you don't move.
To do it, just get on you flying mount and find a spot on the Skybreaker where you "land" but the ship keeps moving without you. You should look like you are sitting on your mount and the ship keeps moving away. Once you manage that, wait till the ship clears before you dismount just in case. After you dismount you will be standing there in mid air. You can cast, do emotes, turn around. Just don't jump or move in any direction or you WILL fall.
Here are some pics I took after I found it.
Me dancing above Icecrown
Me summoning my imp.
He falls to his death though.
Let me know if anything isn't clear and I'll try to explain better. I had one random pally come check me out, he even did it too!
I had an idea since I am a warlock also. I could get two other people to do it close to me so we could summon random people and watch them fall.
its epic ....o the flame and QQ i can almost picture it. 
strange
