Ohh man this is interesting...

... Really depends on the mood
I killed with cabbages using Telekinesis before... take too long though, but hilarious when you actually pull it off.
Once, I was able to trick a forsworn to walk off a cliff by pickpock his weapon and place it on a rock underneath the cliff... I remembered I was in stitches after that.
Other times, I rout giants into bandit camps and villages... Take a while, but it's all sort of awesome seeing them rocket people away.
When I feel sad, I just cast Dragonskin and pick up a greatsword and impale folks with my Dremoras, who was equally stabby.
