I haven't killed anyone yet with odd methods, but I plan to try killing someone by throwing buckets at them. If it works... It will leave a funny mental picture either way. Now for the crazy, funny ways you have killed someone.

I once used unrelenting force on some woman in a tower, she went flying off a cliff into water, she then toppled over a waterfall and died at the bottom

Possibly a spoiler:

I killed Grelod the Kind as a werewolf and fled from town because I didn't want a murder rap. XD

I came across some angry bandits and there was somewhat of a ledge seperating us. One of them choose not to go around it and charged me only to fall down.

But I don't know if it was funnier than me somehow, between dodging blows, getting the Mammoth that was chasing me at level 8 stuck in the mud. I managed to pepper it down to a sliver of health before it got itself unstuck and came after me, I left a fire rune for it though.

I decapitated someone with a Shiv once.

It's not possible but hey, videogames Ammirite?

An ice spike to the ass...

I got tired of listening to Heimskr talk about the future of Skyrim, the future of TAMRIEL!!! so I took the Nightingale and put dwarf arrows in his face and then ran for my life from the town guard of Whiterun. Can't stand that guy.

Haven't tried this but I imagine placing a rune then using the throw voice shout to draw someone into it would be good for a laugh.

I have did a couple fun kills with unrelenting force. As you know in some of bandit camps/forts are those traps outside which drops stones on you. I tried to shout a bandit down from the tower before he opens the trap put I was little late because the trap opened just at the moment I shouted. Well my shout throw most of those stones up to the tower and they killed the bandit. Another one was in a civil war where I shouted seven or eight Imperial soldiers down from the wall at one time. When I did this I was on a ground inside the fort's walls and soldiers were far above me on the wall. They were dropped at the outside of fort but I never seen them again.

Did a whirlwind sprint into a grounded dragon by mistake, went inside it. I just attacked it from the inside. Best glitch ever.

Managed to lure some Forsworn into one of their spike traps, draugr have also been prone to trigger their own traps.

I'll often lure the mobs and shoot the trip plates. XD

I used telekinesis to murder someone with a bucket on my Nightblade. Got them to a sliver of health and pelted them with it over and over. I wish there'd been a spoon nearby, could've been more hilarious to get a kill with a spoon. There's a mod out now on the Nexus that supposedly makes telekinesis stronger, but I haven't tried it yet.
Lol I read that part in his voice. Good voice actor for that to happen I guess. But yeah, I killed him on my Nightblade too.

I have a level 50 Thief with a Daedric bow doing 280 damage. Last night I went to fetch a Drum for the dean of history at the Bards College. So I get to the place and I realise it's quite a low level dungeon. But it has ghosts which I'm weary of because I've met some who can be quite deadly. As I sneak around a corner two of them spawn almost on top of me and I catch such a fright that I misdraw my bow, causing the arrow to travel only a few inches. It hits the ghost closest to me anyway and he dies instantly. I'm like "Okay, I am now officially the god of Archery". Low level dungeons are no fun at that level.

I remember being up somewhere high, can't remember the place, and I was gonna fus-ro-dah a bandit off the edge. When I do it and he's flying he gets pelted with an arrow from Lydia killing him before the fall did. Was kinda funny.

It's always a good bit of fun sending my followers flying off the roof of the college of Winterhold.

"Hey, you stand over here."

"Okay, Anything else?"

"Yeah just one more thing... FUS.... ROH DAH!"

The look on their face as they go cartwheeling off the side is priceless.

Just did the 'Rise in the East' side quest and as I was approaching the end, fireballs were raining everywhere. I was fighting my way back out to shore, and had come to the last bandit.

I went over to kill her, dual flurried and the decap animation fired off.

I lobbed off her head just as a fireball slammed into her and she went sailing into the air.

Amazed, I followed her trajectory and she landed on a banner waving in the wind.

The banner was waving horizontally in the wind, and she just kept getting tossed into the air like she was on a trampoline.

That alone was weird enough, but as I was approaching the NPC to end the quest... a fireball lands and the decapitated head goes sailing right past my face and disappeared into the ocean somewhere on the horizon.

She never stood a chance.

Target practice

Fighting three draugr Deathlords, runing around avoiding their attacks atop a tall ruin. They lead me into a corner (edge), but I sprint pass them, turn around and Fus Roh Do them off the edge. They were insanely powerful, but couldn't survive a mere 50 foot drop. Too bad none of them took the time to learn the etheral form shout.

Spawning 20 dremora lords is always my favorite way of killing someone....

The Flaming Familiar suicide bomber-wolf thing was good for a few chuckles.

This isn't hilarious but it was awesome when I did it. With my sneaky character I shoot an arrow to hit stone stairs because I knew that the Forsworn Briarheart will go to check out what that voice was. When he investigated it I sneaked in his tent and waited until he came back. And then just a beautiful assasination finisher with a dagger.

I decided Lydia is an idiot and in no way shape or form should be allowed to leave the confines of Whiterun after this happened :

I'm in one of the first draugr places trying to be all sneaky , Lydia's having none of that for some odd reason. Still have no idea of why this happened. I spot a spike wall and it's corresponding floor plate so I'm trying to "inspire" her to avoid it by inching around the outside of it , maybe she'll follow closer. WRONG. Lydia's just flopping about the way she likes , goes in front of me , triggers the spike wall and gets flung into the next area kneeling. She then gets up runs back to me with 3 draugr in tow with a goofy half-smile on her face , triggers the wall again , narrowly avoiding it herself and splatting all 3 draugr who were then extremely easy to finish off.

After the dust clears and I move on a bit to scout the area Lydia says,"I don't like the looks of this....."

In Geirmund's Hall there is a Draugr Scourge on an elevated platform that has two rickety wooden bridges that are elevated (until you lower them). He was shooting arrows at me and since my Archery skill was too low to kill him quickly enough I used the Unrelenting Force Shout (all 3 words) and knocked him off to his death. I guess he didn't know...

I was sprinting through a cave earlier and ran into a pile of bones that initiated a hilarious pinball scene earlier.

I whirlwind sprinted to a closed door and kicked a deer skull into a wall, it hit me and took off a big chunk of my health and then went flyiing down the tunnel like a bullet into the damn mage chasing me. I panicked and chugged a potion and turned around to fight him, thinking he was right behind me, but I saw his lifeless body twitching next to the skull still spinning next to him.
