Looking for LoL challanges for youtube channel

Starting a new youtube channel with a friend and I had the idea of recording in-game challenges that you guys come up with. An example of this would be Tank Soraka. Of course counting as a successful completion would be going positive. So if you guys have any ideas for challenges it would be great if you could think of some for us. :)

Edit: A better example of this would be crit nasus.
