So much fun to do that to enemy Akalis as Anivia. Oh, you put down your little invisibility circle? I'll just overlay my ult with this and.....Well you're gonna have to come out eventually, girl!

Enemy 
and 
surround and wait for it to wear off.
So you locked yourself down and can't move anywhere? Here, let me help you stay that way. BWRAHAHAHA!
I was playing Ahri and being chased by Zed. We both had basically no HP left (maybe 5-10% each). I threw my q out and Zhonya. Zed continues to run behind to me. Ball returning hits him them a wave of minions hits him and he dies.
My favorate is when you're playing full AP Zilean and you drop a double bomb on top of them
Priceless
