This was the most hilarious incident I have faced thus far....
I was walking through the woods a spotted a moose. Instead of running he stayed perfectly still. As I walked by him his head followed me. I stopped about three feet away from him. We looked into each other's souls. While we both stood there the silence was broken by a horrible noise. A dragon crashed down on us and killed us both in a matter of seconds.
Now that I think about it....maybe he was standing still to avoid the dragon and was looking at me like "what the hell are you doing bro! Stop moving!"

I was walking up a steep steep hill, and when I was almost at the very top and very proud that I hike the distance, a snow bear growled. I barely managed to kill it, but it's limp body slid and rolled ALLLLL the way down the path I just took up.. gotta love ragdoll physics.

My brother keeps getting randomly attacked by townsfolk for no reason. It's pretty funny.

I saw a dragon flying overhead and I started shooting arrows. I shot 200 iron arrows when I realized:

1. I didn't hit the dragon, not even once

2. The dragon didn't know I'm there and just flew away

....

During the game I didnt pay much attention about giants other than I knew they wont hurt you if you dont hurt them. Well I didnt know they were particular about their camps. I was hiking up a mountain and got close to one. I saw one stamping his feet at me. I didnt get the hint. I got closer and then was bunted 200ft into the air and died. It was awesome.

A random dragon attacked me and some mammoths and when he landed the mammoths be the hell out of him in seconds. =)

Came across a bear in the woods so decided to shoot it, he didnt see me and decided to kill a random hunter behind him who was running from a troll, this 3 way fight then got even more amusing when a spriggan turned up : /

I took a peek in the Dwemer Museum and slipped inside of the room in the back where you're not allowed to go. I thought I was all alone so I had some fun setting off traps. Then just as I turned a valve around a guard started talking to me from behind to tell me I had to leave, but before he could utter more than a few words some sort of explosion was fired off the ceiling and killed him. It felt so natural I thought it had to be scripted in...but it was truly a coincidence after all haha.

This is the funniest thing that ever happened to me!

ran off a cliff chasing a bunny with a battle axe

This JUST happened.

After completing a certain quest in a certain town.. well, there were dead guards. EVERYWHERE.

Wandering beggar spots one, and starts to loot it, followed by, "You shouldn't just leave things around to trip over."

Oh Bethesda. <3

This happened in Bleak Falls Barrow,

There is a room there with a pressure plate that will cause a spiked door to slam into the pour sap stading on it.
So being overmanned by 3 Draugr guards I shout my nordic cry to send them fleeing for 30 secs
and they all run away into that hallway, the first one hits the pressure plate and they all get a hearthy greeting from the trapdoor.

2 of em flew across the room straight over my head and one was stuck between the square shaped opening in the trapdoor's spiked bars.

Giant = Deadly moving catapaults.
Me = The poor schnub getting swung up into the Stratosphere. c:

I had quite a laugh watching a dragon get beat up on by a couple of horses

In one of the very first caves I was exploring I noticed a symbol on the floor. It was obviously a trap, so I stepped on it to see what it would activate. It apparently activates a spiked wall that moves near the speed of light. I was thrown all the way across the cave!

I thought I'd say hi to a giant and he sent me on a one way trip to the moon

A mammoth chased me from Dawnstar to Solitude. I managed to evade it by jumping in the water and swimming for my life. On the opposite bank I started celebrating... Only for a colony of gigantic seals to kick my ass. That'll teach me to let my guard down!

Within my first two hours of playtime I happened upon a nord warrior for hire.

He's a pretty stout fellow. Always willing to tank for me while I plink enemies with arrows.

He's none too bright though. Often times when I'm lining up that perfect shot, he darts in front of me and takes one in his hide.

The funniest part is, it's almost ALWAYS in his head. I lol a bit every time.

This happened to my friend and I.
On a certain quest there involves a shiny light coming out of the ground. So obviously the first thought to cross our mind was..."I should stand on that!"
Only to have my body flung off the side of the mountain by an explosion underground apparently made by molemen!

I had unlocked all of force push shout but I was still no match for giants, so I decided to provoke two of them and have them follow me up to a cliff. Blow them off and go down and loot their bodies.

I was wearing Thieves Guild armor and casing a house, waiting for NPCs to stop walking by, etc. so I could go into sneak mode and pick the lock. Well a guard walked up and just stood looking at me. I didn't move, waiting for her to continue her patrol or leave. Finally she said: "You're not fooling anyone, you know. I recognize Thieves Guild armor when I see it. We all do. We're not stupid. You better stay out of trouble." I was shocked at how . . . intelligent . . . that behavior was on the part of an NPC. I stood still waiting for her to leave and she just kept watching me. I finally had to leave the door of the house and walk away myself! I get the message officer, moving along!

I was heading East of Whiterun along the river with that housecarle companion (can't think of her name :/) Anyway we headed along the North side and came across a tall bridge than connected cliff sides and crosses the rive. As we headed up 4 bandits were alerted and a fight began. First two bandits were taken out on the way up to the bridge and then I headed across. She stayed back and used her bow. I killed the third bandit with some trouble (trying to stay on the small bridge). The fourth was upon me in seconds and we traded blows for a moment.

I decided to use my Force push shout and sent him closer to the edge. he recovers and readies himself once more yelling "is that all you got!?" Right then an arrow goes straight through his neck and his body falls to the river below. I nearly fell off my chair in laughter. XD

I was chasing a bunny through the forest, It lead me to a cliff and ran right off. I just stood there, Looking down at the bunny rolling down a sheer cliff. I was amazing.
